MACAW (Medium Access Collision Avoidance Wireless) is a new MAC protocol for wireless LANs proposed by Bharghavan et al. Ref. 2 based on Karn"s MACA protocol Ref.3. In this thesis the performance characteristics and operational behavior of the protocol are investigated The approach taken was to simulate the protocol by OPNET 2.4c of MIL3, Inc. and determine the utilizations and mean delay times of the transmitters under various operational conditions. Also a new performance measure was defined in terms of utilization and mean delay time. Our investigation has shown that the optimum performance of the MACAW protocol occurs at approximately 50% channel load. We have also shown the importance of the backoff algorithm, and finally, we have shown that carrier sensing dramatically improves the performance of the protocol for high channel loads. Simulation results showed that decreasing the backoff increase rate by 15% gave twice as good performance results for the small number of transmitting nodes cases. When carrier sensing was introduced to the protocol, dramatic performance increases resulted under heavy loads (60% to 80% channel loads). Carrier sensing also pushed the optimum performance channel load threshold from 50% to 60%. Distribution Limitation(s):

Design of Simulation Introduction. Design procedure followed to create this simulation is explained in this chapter. Improving the efficiency of the energy consumption across the wireless sensor networks is the main aim of this Energy Efficient Wireless Sensor MAC Protocol project and to evaluate the research two scenarios are created and the actual design followed to create these scenarios is. In contrast to previous simulation studies of the MAC protocols [2,13,23], the performance analysis we present here is based on a mathematical model. This model not only differs from previous analytic models of the protocols [3,6,7,10], it is also different from the other techniques in the CSMA literature [1,5,12,14,15,17–20].
The purpose of this book is first to study MATLAB programming concepts, then the basic concepts of modeling and simulation analysis, particularly focus on digital communication simulation.
