Secured Energy Conserving Slot-Based Topology Maintenance Protocol for Wireless Sensor Networks

Topology Maintenance Protocols are vital elements that influence Wireless Sensor Networks. These protocols strive to conserve energy and to prevent collisions during communication. In this paper, a Secured Energy Conserving Slot-based Topology Maintenance Protocol, which serves its purpose by overthrowing several existing issues such as energy deterioration and memory overhead, is proposed. Energy conservation is achieved by node behavior based on timeslot. Hence for a particular timeslot, only certain count of nodes remain in work cycle, and the remaining nodes remain in the state of sleep. This conserves energy at its best, which in turn improves the lifespan of the network. Additionally, the issue of memory overhead is resolved by allowing only direct communication between the node and the base station, and hence the base station directly authenticates the constituent nodes. This work widens its scope by focusing on security breaches too. We introduce five attacks to the system; however, the system proves its resilience. The proposed work outperforms the existing system in terms of energy conservation, increase in network lifetime and less memory overhead.
