We present the results of computer simulation of a new medium access control (MAC) protocol for a photonic ring network based on a combination of wavelengthand time-division multiple access (WDMA/ TDMA). The simulations show that the proposed protocol offers maximum throughput in excess of 90% of total network capacity, although for delay-sensitive traffic it is necessary to limit the offered t...

Wireless communications are becoming an important part of our everyday lifestyle. One major area that will have an enormous impact on the performance of wireless ad hoc networks is the medium access control (MAC) layer. Current random access MAC protocols for ad hoc networks support reliable unicast but not reliable broadcast. In this paper, we proposed a random access MAC protocol, Broadcast S...

Medium Access Control (MAC) protocol consists of sets of rules that determine which node is allowed to access the transmission medium. It provides mechanism for collision avoidance such that interfering sensor nodes do not transmit at the same time. In the literature, researchers have proposed different MAC protocols with features aimed at improving energy efficiency and thereby prolonging the ...

MANET is a promising networking technology for tactical network. The behavioural characteristics of MANET like self-forming/healing and bandwidth efficiency mainly depends on the design of underlying MAC protocol. The protocol also plays an important role to meet the dynamics of tactical environment which is characterized by arbitrary and dynamic node topologies along with continuously changing...
