User authentication and secret session key exchange between a user and a sensor node are important security requirements of wireless sensor networks for retrieving the important, confidential and real time information from the sensor nodes. In 2014, Choi et al. proposed a elliptic curve cryptography based user authentication protocol with enhanced security for wireless sensor networks and after security analysis of their protocol we find that their protocol has some security drawbacks such as (1) no resilient against node capture attack, (2) insecure against stolen smart card attack (3) vulnerable to sensor node energy exhausting attacks. Based on the security analysis we propose a scheme to withstand the various security weaknesses of WSNs. Furthermore, the comparative security and computational performance analysis indicate that our proposed scheme is relatively more secure and efficient.

Wireless sensor Network is a network of hundreds or thousands of sensor Nodes. These Nodes communicate with each other with short range radio signals. These nodes are small in size and have very limited battery power. The focus of the researchers is always on developing the routing protocols having the low power consumption to enlarge the life time of the network. In this paper we have proposed Energy Aware Diffusion for wireless sensor networks which is based on directed diffusion. In Directed Diffusion The path selection done by the Sink Node is based on the quality of the path (i.e. the path will be selected based on the higher data rate). In our approach the sink will select a path which will require minimum energy to send the data from source to sink. The experimental results shows that the proposed algorithm works better in terms of network life time, average end to end delay and energy savings.

作者： Rohankar, Rupali Katti, C. P. Kumar, Sushil Jawaharlal Nehru Univ Delhi India

Application of wireless devices is increasing day-by-day in all areas of human life throughout the world. Most of these devices are based on tiny sensors that collect information from surrounding environment automatically without any human intervention when they are deployed in the environment thus creating wireless sensor networks. These tiny sensors are highly energy constrained due to their limited battery, storage, processing power and communication capacity. The constraint makes 'Energy Efficiency' one of the most investigated themes among researchers in wireless sensor networks. In the past, various energy efficient data collection techniques have been suggested in the literature. This paper presents a qualitative review of recent advances in data collection techniques in WSN. The review classifies each of the considered techniques based on underlying topology. A second level categorization of these techniques is done based on energy saving scheme used. A comparison of these techniques is provided for qualitatively evaluating these techniques. The review concludes with a discussion on limitations of the considered techniques. (C) 2015 The Authors. Published by Elsevier B.V.

Due to energy limitation of sensor nodes, the conventional security algorithms with high computation complexity are not suitable for wireless sensor networks (WSNs). We propose a compressive sensing-based encryption for WSNs, which provides both signal compression and encryption guarantees, without introducing additional computational cost of a separate encryption protocol. In this paper, we also discuss the information-theoretical and computational secrecy of compressive sensing algorithm. For proposed WSN, if only a fraction of randomizer bits is stored by an eavesdropper, then the probability that he/she cannot obtain any information about the plaintext approaches zero. Simulation results show a trade-off can be made between the sparsity of a random measurement matrix and the number of sensor nodes used to reconstruct the original signal at the fusion center.

Wireless sensor network consists of micro electromechanical sensor nodes which are operated by battery power. sensor network has emerged as an important supplement to the modern wireless communication systems due to its wide range of applications. The modern researchers are facing the various issues concerning sensor networks more graciously. However, offering security to an energy constrained network of sensor nodes is still a challenge. The proposed scheme named as Secure Cluster Based Routing Scheme (SCBRS) for Wireless sensor networks adopts a hierarchical network model coupled with low weight security mechanisms in order to conserve energy as well as offer security to the network. Elliptic Curve Cryptography (ECC) based public key cryptography, Elliptic-Curve Diffie-Hellman (ECDH) key exchange scheme, nested hash based message authentication codes (HMAC) and RC5 symmetric cypher are the light-weight security methods used by the proposed scheme. Simulation results prove that SCBRS performs better than Tree Based Protocol for Key Management in Wireless sensor networks in terms of energy efficiency and security. SCBRS also performs better than Secure Hierarchical Routing Protocol (SHRP) in fields where security is the most important issue.

international symposium on Turbo Codes and Related Topics

作者： Fabian Steiner Patrick Schulte Fachgebiet Methoden der Signalverarbeitung Technical University of Munich Institute for Communications Engineering Technical University of Munich

In this work, the design of robust, protograph-based low-density parity-check (LDPC) codes for rate-adaptive communication via probabilistic shaping is considered. Recently, probabilistic amplitude shaping (PAS) by Böcherer et al. has been introduced for capacity approaching and rate-adaptive communication with a bitwise-demapper and binary decoder. Previous work by the authors considered the optimization of protograph based LDPC codes for PAS and specific spectral efficiencies (SEs) to jointly optimize the LDPC code node degrees and the mapping of the coded bits to the bit-interleaved coded modulation (BICM) bit-channels. We show that these codes tend to perform poor when operated at other rates and propose the design of robust LDPC codes by employing a min-max approach in the search for good protograph ensembles via differential evolution. The considered design uses a single 16 amplitude-shift-keying (ASK) constellation and a robust 13/16 ≈ 0.813 rate LDPC code to operate between 0.7 to 2.7 bits per channel use. For a blocklength of 16 224 bits and a target frame error rate of 10 -3 the proposed code operates within 1.32 dB of continuous AWGN capacity for 0.7 bpcu to 1.3 bpcu and within 1.05 dB for 1.3 bpcu to 2.7 bpcu.

In this paper we have analyzed the distributed node clone detection techniques in wireless sensor networks. Although there are many protocols in literature proposed for node clone detection, but we have discussed some efficient protocol like LSM and RED under the category of witness based node clone detection. We have analyzed the detection level, memory, and energy overhead of LSM, RED and proposed protocol. We have presented an approach for the optimization of witness based distributed node clone detection. For the validation of proposed protocol performance, we have provided mathematical as well as simulation results for the various parameters of the WSN.

We consider the channel access problem arising in opportunistic scheduling over fading channels, cognitive radio networks, and server scheduling. The multi-channel communication system consists of N channels. Each channel evolves as a time-nonhomogeneous multi-state Markov process. At each time instant, a user chooses M channels to transmit information. Some reward depending on the states of the chosen channels is obtained for each transmission. The objective is to design an access policy that maximizes the expected accumulated discounted reward over a finite or infinite horizon. The considered problem can be cast into a restless multi-armed bandit (RMAB) problem with PSPACE-hardness. A natural alternative is to consider the easily implementable myopic policy. In this paper, we perform an theoretical analysis on the considered RMAB problem, and establish a set of closed-form conditions to guarantee the optimality of the myopic policy.

IEEE international symposium on Dependable, Autonomic and Secure Computing (DASC)

Device-to-Device (D2D) and Massive Machine Communication (MMC) are believed to be the cornerstones of future 5th generation (5G) cellular technologies. As a method to increase spectrum utilization, extend cellular coverage, and offload backhaul traffic, D2D has been recently incorporated into Release 12 of 3rd Generation Partnership Project (3GPP) Long Term Evolution Advanced (LTE-A) specifications. Devices in physical proximity can thus discover each other and communicate via a direct path using licensed LTE spectrums. Leveraging on the ubiquity of cellular coverage and harnessing LTE-A D2D for networks with massive number of machine-type communications, such as large-scale sensor networks and vehicular networks, introduces a paradigm shift and opens up new opportunities for proximity-based services. In this paper, we propose a novel radio resource allocation method for D2D discovery in clustered MMC networks. With a large number of nodes, the proposed method can still maintain the signaling overhead at a reasonable level while achieving high discovery rate. Experimental results show that the proposed approach significantly outperforms the existing 3GPP random resource allocation mechanism.
