Orthogonal frequency-division multiplexing (OFDM) is an appropriate solution to combat inter-symbol interference (ISI) caused by multi-path propagation in wireless communications. OFDM-based wireless communication systems become more and more popular and the base-band algorithm is one of the significant parts of the systems. In this paper, we present the design and implementation of base-band algorithms for OFDM-based wireless communication systems. the results show that the designed algorithms are effective for implementation of the system.

the recent advancements in wireless sensor hardware ensures sensing multiple sensor data such as temperature, pressure, humidity, etc. using a single hardware unit, thus defining it as multi-sensor data communication in wireless sensor networks (WSNs). the in-processing technique of data aggregation is crucial in energy-efficient WSNs;however, withthe requirement of end-to-end data confidentiality it may prove to be a challenge. End-to-end data confidentiality along with data aggregation is possible withthe implementation of a special type of encryption scheme called privacy homomorphic (PH) encryption schemes. this paper proposes an optimized PH encryption scheme for WSN integrated networks handling multi-sensor data. the proposed scheme ensures light-weight payloads, significant energy and bandwidth consumption along with lower latencies. the performance analysis of the proposed scheme is presented in this paper with respect to the existing scheme. the working principle of the multi-sensor data framework is also presented in this paper along withthe appropriate packet structures and process. It can be concluded that the scheme proves to decrease the payload size by 56.86% and spend an average energy of 8-18 mJ at the aggregator node for sensor nodes varying from 10-50 thereby ensuring scalability of the WSN unlike the existing scheme.

Hybrid wireless-optical networks provide the inexpensive broadband bandwidth, vital for modern applications, as well as mobility and, scalability required for an access network. However, in order to provide satisfactory Quality of Service (QoS) on such a non-homogeneous network, innovative designs are required. this paper proposes a novel mechanism to significantly improve the delay guarantee, while maintaining throughput, by predicting the incoming traffic to ONUs. Based on the proposed method, two dynamic bandwidth assignment algorithms are proposed. the performance of the proposed algorithms are evaluated by extensive simulations. the results show that the delay bound of delay-sensitive traffic classes, is decreased by a factor of two, while throughput remains the same.

In this paper we propose the usage of a prediction technique based on Markov Chains to predict nodes positions withthe aim of obtain short paths at minimum energy consumption. Specifically, the valuable information from the mobility prediction method is provided to our distributed routing algorithm in order to take the best network decisions considering future states of network resources. In this sense, in each network node, the mobility method employed is based on a Markov model to forecast future RSSI states of neighboring nodes for determining if they farther or closer within the next steps. the approach is evaluated considering different algorithms such as: Distance algorithm, Distance Away algorithm and Random algorithm.

Real World Edutainment (RWE) is an educational computer game focusing on a game story and human-human interaction in the real world and aims mainly at increasing learning motivation. At an educational event, children learned phenomena of light through the RWE where they were able to observe real phenomena (realworld objects) and view multimedia learning materials.
