An efficient medium access control (MAC) protocol is critical for the performance of a wireless sensor network (WSN), especially in terms of energy consumption. In this work we discuss the efficiency of S-MAC, a well-known MAC protocol for WSNs, and propose an improvement on the protocol. Via an extensive simulation study considering the cases of both simple and complicated topologies, the enhanced...
Wireless sensor networks (WSNs) have a wide range of invaluable civil and military applications. Nodes in WSNs act as information sources, sensing and collecting data samples from their environment. They perform routing functions, creating multi-hop wireless networking fabric that conveys data samples to other sensor nodes. A number of important performance measures have to be considered in designing...
