In this paper, an efficient coordination mechanism is designed for Wireless Sensor and Actor Networks (WSANs) to perform reliable actions in the event area. It is a Voronoi diagram based energy and delay aware coordination mechanism using two-level hierarchical clustering protocol. In the first level, every actor calculates the sensor Voronoi region using sensor range and residual energy. In the second...
Once sensors detect an event they always have to route the data to base station where the data is processed. Since sensors usually have concerns regarding coverage, energy, processing power and memory, etc achieving Quality of Service is hard in sensor networks. Therefore to deal with such issues of sensors and to maximize the Quality of Service, initially the two tiers Heterogeneous Sensor Networks...
