Hex-grid based Routing Protocol in Wireless Sensor Networks

This paper presents routing protocol based on hex grid in WSNs, a power saving technique for multi-hop ad hoc wireless networks that reduces energy consumption without significantly diminishing the capacity or connectivity of the network. Proposed protocol builds on the observation that when a region of network system has a sufficient density of nodes, It is a distributed, delegated algorithm where nodes make local decisions on whether to sleep, or to join a forwarding discovery mode as a cluster head. Each node bases its decision on an estimate of how many of its neighbors will benefit from it being awake, and the amount of energy available to it. We give a algorithm where coordinators rotate with residual battery, demonstrating how localized node decisions lead to a connected, capacity-preserving global topology. Improvement in system lifetime due to change cluster head increases as the ratio of idle-to-sleep energy consumption increases. Our simulations show energy model. Additionally, This protocol also improves communication latency and capacity.
