Wireless sensor networks and, particularly wireless body area networks (WBANs) are the key building blocks of upcoming generation networks. Modern health care system is one of the most popular WBAN application and a hot area of research in subject to present work.In recent years, research has focused on channel modeling, energy conservation and design of efficient medium access control (MAC) schemes. Less attention has been paid to the path-loss performance analysis. In this work, we propose LAEEBA (Link-aware and Energy Efficient scheme for Body Area Networks) which is a reliable, pathloss efficient and high throughput routing protocol for WBANs. The characteristics of single-hop and multi-hop communication schemes have been utilized to reduce path-loss effects and increase network lifetime. A cost function is proposed to selectthe forwarder node on the basis of has high residual energy and minimum distance to sink. Residual energy parameter balances the energy consumption among the sensor nodes while distance parameter ensures successful packet delivery to sink. Simulation results show that LAEEBA protocol maximizes the network stability period and nodes stay alive for longer time; which contributes to sufficient decrease in the path-losses occurring in the links connecting sensors on a human body and hence transferring of data with much less losses.Results show better performance of our proposed protocol as compared to its given variants.

Due to small size of sensor nodes deployed in Wireless Sensor Networks (WSNs), energy utilization is a key issue. Poor channel conditions lead to retransmissions and hence, result in energy wastage. Error control strategies are usually utilized to accommodate channel impairments like noise and fading in order to optimize energy consumption for network lifetime enhancement. Meanwhile, cooperative communication also emerges to be an appropriate candidate to combat the effects of channel fading. Energy efficiency of cooperative scheme when applied with Automatic Repeat Request (ARQ), Hybrid-ARQ (HARQ) and Forward Error Correction (FEC) is investigated in this work. Moreover, the expressions for energy efficiency of Direct Transmission, Single Relay Cooperation and Multi Relay Cooperation are also derived. In all, our work is focused towards energy optimal communication in WSNs. Our results show that error control strategies with cooperative schemes can significantly enhance system performance in form of energy optimization.
