| Popis: | In general, the energy consumption in a Wireless Body Sensor Network (WBSN) is a critical issue. Specifically the nodes that are placed next to the sink node consume more energy which limits the network lifetime because all biomedical packets are aggregated through these nodes forming a bottleneck zone. Therefore, this work proposes a novel mathematical model for body area network (BAN) topology to explain the deployment and connection between biosensor nodes, simple relay nodes, network coding relay nodes and the sink node. The model uses the coordinate duty cycle (CDC) technique and Random Linear Network Coding (RLNC) to improve the energy efficiency in the bottleneck zone. A mathematical model for WBSN has been designed, and it was apparent that energy consumption is reduced with the proposed mechanism; this paper details the results. |
