A performance evaluation of S-MAC protocol in combination with energy efficient protocols for Wireless Sensor Networks

This paper provides a performance evaluation of the existing S-MAC protocol in combination with energy efficient protocols that are used in Wireless Sensor Networks. The whole work is mainly concentrated on the study, analysis and performance evaluation of the existing S-MAC protocol. We have concentrated on improving the power consumption of the S-MAC protocol, by using the OLSR routing protocol. The improvement of the S-MAC protocol can increase sensor nodes' lifetime and thus, network connectivity and survivability. The evaluation and test results show that the combination of S-MAC protocol with OLSR consumes less power compared to the rest of the schemes using the routing protocols AODV, DSR and DSDV.
