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...
A new scheme, combining medium access control (MAC) with traffic policing for next generation wireless networks, is proposed in this work, in order to provide a flexible solution for the integration of multimedia traffic over noisy high capacity links. The most attractive features of our scheme are: a) its flexibility, which allows it to adapt easily to wireless channel of various capacities, and...
