Wireless sensor networks will play an important role in the next generation pervasive computing. But the character of wireless communication brings a great challenge to the security management measures used in the communication protocols. These measures are different from conventional network security management methods. This paper proposed a security management model for self-organizing wireless sensor networks based on intrusion detection. It can prevent most of attacks. Then an analysis of each layer of networks in our security model is discussed and the security management measures in the data link layer and network layer are described in detail especially.

Energy efficiency is one of the determining factors for survivability and lifetime of wireless sensor networks (WSNs). In this paper, an energy optimization approach based on cross-layer for wireless sensor networks is proposed, which consider the joint optimal design of the physical, medium access control, and routing layer. The approach focuses on the computation of optimal transmission power, routing, and duty-cycle schedule that optimize the WSNs energy-efficiency. The approach is validated on a CROSSBOW's MicaZ mote platform, and evaluated using the TOSSIM simulator. the simulation results show that it is an energy-efficient approach and able to achieve significant performance improvement as well.

sensor networks are the next generation of technology for use in various applications, including tracking, monitoring and control. However, sensor networks still have some inherent security and hardware problems. The cluster routing scheme has been proposed in attempt to reduce duplication reports. Moreover, statistical en-route filtering (SEF) has been proposed to detect and drop the injected fabricated report found in the sensor network. When SEF method is applied in cluster-based sensor networks, their detection capabilities may be quite poor because the proposed schemes do not consider each possible feature that may be present. To solve this problem, we propose a cluster adaptation method to enhance the performance of SEF. The proposed method uses a fuzzy logic approach to form an efficient cluster for SEF. The sufficient performance of the proposed method is shown by the simulation results.

Route optimization support in mobile networks is one of the most important concerns in next generation networks (NGNs). NGNs require an efficient route optimization scheme, optimized specially to support nesting of mobile networks. We propose an Extended Mobile IPv6 route optimization (EMIP) scheme to enhance the performance of nested mobile networks. EMIP scheme is based on MIPv6 route optimization and the root Mobile Router (MR) performs all the route optimization tasks on behalf of all active Mobile Network Nodes (MNNs). Thus, the network movement remains transparent to sub MRs and MNNs. It modifies only MRs and MNNs leaving other entities untouched and is more efficient than the Network Mobility Basic Support protocol (NEMO BS). We carried out extensive simulation study to show that EMIP performs better than NEMO BS and Reverse Routing Header (RRH, a well established route optimization protocol) with respect to TCP throughput and round trip time. EMIP effectively reduces unnecessary large travelling route and overhead, thereby enhances performance. It also achieves route optimization between the mobile network nodes inside nested mobile network. ©2009 IEEE.

Automatic generation of Persistent Formations for Multi-agent networks Under Range Constraints

MOBILE networks & APPLICATIONS 2009年第3期14卷 322-335页

In this paper we present a collection of graph-based methods for determining if a team of mobile robots, subjected to sensor and communication range constraints, can persistently achieve a specified formation. What we mean by this is that the formation, once achieved, will be preserved by the direct maintenance of the smallest subset of all possible pairwise inter-agent distances. In this context, formations are defined by sets of points separated by distances corresponding to desired inter-agent distances. Further, we provide graph operations to describe agent interactions that implement a given formation, as well as an algorithm that, given a persistent formation, automatically generates a sequence of such operations. Experimental results are presented that illustrate the operation of the proposed methods on real robot platforms.

A Prioritized Medium Access Control (PMAC) protocol is proposed for wireless sensor networks, based on a binary count down approach. PMAC effectively, eliminates data collision and optimizes channel allocation. Moreover as many networks nowadays compose traffic with several priorities, the simple yet effective design of PMAC offers strict service differentiation for prioritized packets. In this paper PMAC is evaluated by collision probability, reneging/dropping probability, network throughput and channel efficiency. Our simulations show that the protocol effectively supports traffic differentiation and achieves very low pocket dropping (both reneging and blocking) probabilities under the channel capacity When the network is overloaded, it still maintains extremely stable and high channel throughput. It is demonstrated that PMAC performs superior in multihop networks, further proving the advantages of the proposed protocol. Featured with efficiency, simplicity, scalability, fairness, mobility and QoS provisioning, PMAC may be well served for the next-generation wireless networks.

Traditional static spectrum allocation policies have been to grant each wireless service exclusive usage of certain frequency bands, leaving several spectrum bands unlicensed for industrial, scientific and medical purposes. The rapid proliferation of low-cost wireless applications in unlicensed spectrum bands has resulted in spectrum scarcity among those bands. Since most applications in Wireless sensor networks (WSNs) utilize the unlicensed spectrum, network-wide performance of WSNs will inevitably degrade as their popularity increases. Sharing of under-utilized licensed spectrum among unlicensed devices is a promising solution to the spectrum scarcity issue. Cognitive Radio (CR) is a new paradigm in wireless communication that allows sensor nodes as the unlicensed users or Secondary Users (SUs) to detect and use the under-utilized licensed spectrum temporarily. Given that the licensed or Primary Users (PUs) are oblivious to the presence of SUs, the SUs access the licensed spectrum opportunistically without interfering the PUs, while improving their own performance. In this paper, we propose an approach to build Cognitive Radio-based Wireless sensor networks (CR-WSNs). We believe that CR-WSN is the next-generation WSN. Realizing that both WSNs and CR present unique challenges to the design of CR-WSNs, we provide an overview and conceptual design of WSNs from the perspective of CR. The open issues are discussed to motivate new research interests in this field. We also present our method to achieving context-awareness and intelligence, which are the key components in CR networks, to address an open issue in CR-WSN.

The low power wireless communication technology has enabled the development of next generation low cost wireless sensor network One important performance index of routing mechanism in sensor networks is sensor life span. How we utilize limited energy in wireless sensor network, directly affects the lifetime and cost of the network. As sensors are energy constrained by batteries and located for away from the access point. A sensor dies if its battery dies. Since the radio transmission consumes a lot of energy, we propose network routing protocols to save energy to prolong the sensor lifespan.

Emergency communication in heterogeneous networks with fragile connectivity is a challenging task. Emergency Delay-Tolerant Network (EDTN) is a new network architecture based on the concept of Delay Tolerant networks (DTNs) to provide emergency service. However, existing transport protocols like TCP are not suitable to provide emergency service well with instable bandwidth and connectivity, because EDTN use opportunistic forwarding to achieve end-to-end communication. The paper proposes a Hybrid layered network architecture for EDTN based on cluster classification without infrastructure. Especial investigation in the network model by introducing the data layer and control layer is also brought forward, which presents the various DTNs nodes and layer information interactions based on Session Initiation Protocol (SIP). Moreover, we have extended the usage of EDTN in next generation network, which leads to the insights for the future theoretic study and project design.
