Multiple Parameters based Approach to Estimate band width in Mobile Ad Hoc Networks

Mobile Ad hoc Network (MANET) is a self-organized network where network is set up on the fly. Some of the issues in MANETs are routing, security, power management, bandwidth management, mobility management, etc. Correct estimation of the available bandwidth is one of the essential components for efficient network resource management and seamless mobile service provisioning of Quality of Service (QoS) guarantee for real time multimedia applications. This paper addresses the problem of estimation of bandwidth in MANETs by considering channel busy time, channel idle time, packet transmission time, and packet retransmission time under the collision conditions and handshaking time. The proposed bandwidth estimation method is simulated in several network scenarios to test its operation effectiveness. Bandwidth utilized parameter is analyzed under different conditions like varying idle time and busy time of the channel, channel utilization ratio, and channel capacity.
