Lifetime Optimization for Target Coverage in Wireless Sensor Networks
Pooja Chaturvedi, A. K. Daniel · 2015
Maintaining the desired coverage level and reliability is a major challenge in the field of wireless sensor networks (WSNs). WSN consists of number of resource constrained and unreliable sensors. In this paper we have proposed a node scheduling protocol based on trust model, which reduces the energy consumption by putting the sensor nodes in the sleep mode. To improve the lifetime we have compared the performance of proposed protocol with Trust Based Probabilistic Coverage Algorithm (TBCA). The proposed Energy Efficient Coverage Protocol (EECP) provides the performance improvement in terms of network lifetime and reliability of the data transmitted to the base station.
