Energy-Efficiency in WSN Based on SCMC Protocol

Abstract

In Wireless Sensor Networks (WSNs) the QoS is considered to be an important factor which is based on the performance of end-to-end delay, energy-efficiency and packet delivery ratio. In WSN, the single path routing mechanism faces a lot of problems in providing a better communication channel, as there is no option for alternative path in case of path failure. This problem can be overcome by implementing multipath routing mechanism with well designed protocol. In this paper, it is intended to propose Single cluster with Multi-hop Communication (SCMC) protocol to achieve better QoS by means of improved bandwidth, packet delivery ratio as well as end-to-end delay. It is a Multi-hop Communication Protocol with a single cluster head that balances the energy level and achieves high energy conservation with increased lifetime. The single cluster forms dynamic multi-paths with multi-members for multi-hop communications. This work is implemented in Ns-2 and compared with ECMP and SPEED protocols. The result shows that the proposed protocol is more effective in terms of minimum delay, low energy consumption and increased delivery ratio than the other two protocols.
