An Energy Efficient Event Coverage in Wireless Sensor Network

Mohammad Ibrahim Adawy, Shahrudin Awang Nor and Massudi Mahmuddin

Wireless Sensor Network (WSN), is a finite set of sensor nodes spatially deployed in the field area. Sensor nodes that sense same event will generate redundant data. Consequently, data redundancy exhausts network resources and increases network overhead. An Energy Efficient Event Coverage scheme (EEEC) is proposed based on integration of Boolean sensing model and Event radius model to determine minimum number of source nodes required to cover event region. The aim of the current study is to reduce the energy nodes consumption and extend network lifetime. The researcher has proposed mathematical model to analyse event coverage, in addition, experimental study has been performed by using OMNet ++ simulation tool to obtain outcomes. Compared with LEACH scheme, the simulation result shows that, the proposed scheme reduced energy consumption of sensor nodes. The current study recommends that the proposed scheme is perfect scheme in which cluster data aggregation extends network lifetime.
