Energy Efficient Sensory Data Collection in Wireless Sensor Networks

Wireless Sensor Networks consist of numerous nodes with sensing, computing and wireless communication capabilities. When WSNs are utilized in safety-critical or highly-reliable applications, two-timing constraints are considered: real-time constraints and network lifetime constraints. WSNs security is required due to it's sensitive information transmission and utilized in a wide range of application like military sensing and tracking, health monitoring, data acquisition in hazardous environments and habitat monitoring. Wireless Sensor network applications involve a group of isolated urban area consisting of sensor nodes monitoring environmental parameters. Our proposed protocol aims at minimizing the general network overhead and energy cost using multi hopping data retrieval process which always ensures sensible energy consumption among various sensor nodes and more network lifetime. This is often achieved through building efficient cluster structures which consist of sensor nodes that can route their measured data to thier assigned cluster head. Energy efficiency is achieved using mobile sinks.
