“…The results show an improvement in packet error rate (PER) and energy efficiency (EE) when measured against source-destination hop length. Furthermore, equations are derived for incremental three-stage relay scenario [ 18 ] and the simulation results [ 19 ] showed an improved PER at the cost of EE. The energy consumption based on various modulation schemes is discussed in [ 20 ] for simple and coded WBAN links.…”

The fabrication of lightweight, ultra-thin, low power and intelligent body-borne sensors leads to novel advances in wireless body area networks (WBANs). Depending on the placement of the nodes, it is characterized as in/on body WBAN; thus, the channel is largely affected by body posture, clothing, muscle movement, body temperature and climatic conditions. The energy resources are limited and it is not feasible to replace the sensor’s battery frequently. In order to keep the sensor in working condition, the channel resources should be reserved. The lifetime of the sensor is very crucial and it highly depends on transmission among sensor nodes and energy consumption. The reliability and energy efficiency in WBAN applications play a vital role. In this paper, the analytical expressions for energy efficiency (EE) and packet error rate (PER) are formulated for two-way relay cooperative communication. The results depict better reliability and efficiency compared to direct and one-way relay communication. The effective performance range of direct vs. cooperative communication is separated by a threshold distance. Based on EE calculations, an optimal packet size is observed that provides maximum efficiency over a certain link length. A smart and energy efficient system is articulated that utilizes all three communication modes, namely direct, one-way relay and two-way relay, as the direct link performs better for a certain range, but the cooperative communication gives better results for increased distance in terms of EE. The efficacy of the proposed hybrid scheme is also demonstrated over a practical quasi-static channel. Furthermore, link length extension and diversity is achieved by joint network-channel (JNC) coding the cooperative link.

Due to emergence of WBAN in real time applications recently, significant research works are reported on communication standards of wireless body area networks (WBANs). The two primary challenges in opportunistic WBANs that are-network management cost reduction and energy consumption reduction in order to deliver the costeffective and reliable services to critical patients in healthcare application. There are number of solutions reported to address this challenges in recent past, however, they failed to cover all the aspects of WBANs communication. In this, project we proposed novel opportunistic communication protocol for WBANs with aim to solve the research challenges not only the energy efficiency and network management cost reduction but also solves the problem of non-reliable nodes data dissemination. First we proposed the novel energy-efficient and distributed network management cost minimization framework for dynamic connectivity and data dissemination in opportunistic WBANs. Then we proposed a pricing based approach for reliable node data dissemination. This can be done by reputation-based incentive methods to motivate participants to disseminate reliable data in participatory sensing system, while minimizing incentive cost for maintaining sufficient number of reliable participants. The simulation results reveal the effectiveness of proposed method.

Abstract. We consider the problem of optimally designing a body wireless sensor network, while taking into account the uncertainty of data generation of biosensors. Since the related min-max robustness Integer Linear Programming (ILP) problem can be difficult to solve even for state-of-the-art commercial optimization solvers, we propose an original heuristic for its solution. The heuristic combines deterministic and probabilistic variable fixing strategies, guided by the information coming from strengthened linear relaxations of the ILP robust model, and includes a very large neighborhood search for reparation and improvement of generated solutions, formulated as an ILP problem solved exactly. Computational tests on realistic instances show that our heuristic finds solutions of much higher quality than a state-of-the-art solver and than an effective benchmark heuristic.
