Energy efficient routing is the paramount point of significance in any wireless sensor network (WSN) so that the network sustains without any human intervention. Various energy efficient protocols have been proposed, multi-level Low Energy Adaptive Clustering Hierarchy (LEACH) being one among these. The multi-level LEACH protocol involves election of cluster heads at various hierarchical levels. If...
Wireless Sensor Networks (WSNs) comprise of large number of sensor nodes, which sense and measure various physical phenomena related parameters and transmit the measured data towards the base station by making use of the neighbouring nodes acting as relay nodes. In order to extend the lifetime of a WSN application, it is necessary to distribute the energy dissipated among the nodes evenly in the network...
The deployment of Wireless Sensor Network(WSN) must be done with some kind of advanced techniques so that it can mitigate the energy constraints. An existing, clustered-based routing protocol known as Low-Energy Adaptive Clustering Hierarchy (LEACH) was studied, the outcome is an improved algorithm based on LEACH. The performance of these algorithms was studied through simulations using OMNeT++. In...
A time division multiple access (TDMA) scheduling protocol is proposed for solving the inter-cluster interference of medium access control (MAC) in cluster-based wireless sensor networks (WSN). Through each cluster-head snooping into the neighbor nodes' networking packets and creating the TDMA schedule based on these packets, the protocol can avoid inter-cluster interference. The protocol is implemented...
