A wireless sensor network (WSN) usually operates in an unreliable wireless environment with energy constraint. Many researchers are primarily interested in energy awareness and communication reliability of WSNs to maximize network lifetime. However, dealing with the conflicting problems of improving energy efficiency and fault-tolerance simultaneously is a challenging task. Most previous studies have...
Cooperative communication (CC) exploits space diversity through allowing multiple nodes cooperatively relay signals to the receiver so that the combined signal at the receiver can be correctly decoded. Since CC can reduce the transmission power and extend the transmission coverage, it has been considered in topology control protocols [1], [2]. However, prior research on topology control with CC only...
In the application of wireless sensor networks (WSN), the balance of energy consumption plays an important role in extending the life cycle of WSN. Aim at energy consumption of Wireless sensors network, a dynamic cluster-based routing protocol based on the greedy algorithm (GDCRP). In the protocol, nodes run for the cluster head according to the energy and location. The elected cluster head has optimal...
