Prolonged lifetime, improved coverage, and load balancing are important requirements in wireless sensor network applications. In this paper, we propose a new clustering protocol-adaptive clustering algorithm based on energy restriction (ACAER), which periodically selects cluster nodes according to their coverage rate and residual energy. ACAER has no assumptions about the distribution or density of...
Clustering sensor nodes is an effective topology control for increasing network lifetime and scalability. It also, balances the load on the sensor nodes. HEED is a well known distributed clustering protocol that uses both energy and communication cost to elect Cluster Heads (CHs) in a probabilistic way. This paper improves HEED protocol using fuzzy logic and a non probabilistic approach for CH election...
The most important issue in designing a data gathering algorithm is how to save energy of sensor nodes while meeting the requirement of application such as sensing are coverage. On the other hand, in the real applications, it is unrealistic to guarantee all sensors have the same energy because they have different energy consumption. In this paper, A cluster based data gathering protocol for heterogeneous...
