Broadcast and Reliable Coverage based Efficient Recursive Routing in Large-Scale WSNs

摘要

This paper presents a Broadcast and Reliable Coverage based Efficient Recursive Routing (BRCER) in Large-Scale Wireless Sensor Networks for Event-Driven Applications with Mobile Sinks (MSs). For data routing in the network, the proposed protocol updates the connectivity list by using local broadcast and multicast announcement. Instead of broadcasting in the whole network, the local broadcasting is used to save sensor node energy which maximizes the battery lifetime of sensors. However, the multicast announcement provides the appropriate path whenever the event activities are performed by MSs. In addition, reliable communication connectivity among sensor nodes, which depends on the surrounding and the deployment of sensor nodes, is also our prime concern for better quality of service (QoS). The main focus of BRCER protocol is to timely route the data with proper load distribution in the network with reliable connectivity. Theoretical concept and simulation results further validate that BRCER protocol can withstand in worse environmental conditions with effective network performance.
