Optimizing the Duration of the Wireless Sensor Network within Smart City

Abstract

The aim of this paper is therefore to propose new and effi-cient mechanisms for the optimization of the lifetime in "WSN: Wire- less Sensor Network", while guaranteeing, at any time of this lifetime, a good networkconnectivity.

To achieve our goals, we have implemented and improved an algorithm called DSMAC (Distributed Scheduling Medium [5].

Acces Control) which is based on the node placement method. In addi- tion, DSMAC allows 100% coverage of the monitoring area, ensures good connectivity of the RCSF and also allows the sensor nodes to save up to 30% of their energy compared to other MAC protocols such asTunableMAC.
