Cluster; Communication; Energy; Power Consumption; Sensor Node.Abstract
Wireless Sensor Network (WSN) requires communication protocols to minimize the energy
consumption. A Cluster-based scheme is proposed as a solution for this problem. A WSN is generally
composed of hundreds and thousands of distributed mobile sensor nodes, with each node having limited and
similar communication, computing and sensing capabilities. The proposed scheme extends High Energy First
(HEF) clustering algorithm and enables multi-hop transmissions. The MIMO scheme prolongs the network
lifetime with 75% of nodes remaining alive when compared to LEACH protocol.
