Fault Tolerant Middleware Multicast Routing in Wireless Sensor Network

Energy consumption, memory and throughput of nodes are crucial factor that constrains the networks life time for Wireless Sensor Networks (WSNs). These are challenges to optimize communication amongst a group of spatially distributed sensor nodes in a wireless sensor network. There are several traditional approaches to overcome these challenges such as to apply clustering techniques to effectively establish an ordered connection of sensor nodes whilst improving the overall network lifetime. In this paper, an improved clustering based multicast approach is proposed that allows any cluster head to be a multicast source with an unlimited number of subscribers, to optimize group communication in WSNs whilst ensuring sensor nodes do not deprecate rapidly in energy levels.
