Abstract :
This paper introduces the Dynamic HMARS (D-HMARS) protocol designed for the Hybrid Radio-over-Fiber Wireless Sensors Network (WSN-RoF) architecture, in which multiple clusters of wireless sensor nodes are connected to a base station via an optical link using Radio-over-Fiber (RoF) technology. The D-HMARS protocol was designed to avoid the problem of occurrence of false positive in the Clear Channel Assessment (CCA) mechanism. Simulation results show that the D-HMARS protocol increases the delivery ratio as well as the effective throughput of the network.
