Abstract: This paper proposes a packet loss ratio-based routing protocol (PLRRP), comprising of admission control and QoS-aware routing algorithm, contention aware admission control and adaptive transmission metric for enhancing the performance of mobile ad-hoc networks. Admission control algorithm optimises the placement of data in each of its reserved bandwidth which avoids collision. Adaptive transmission checks for the available bandwidth and active links for transmission and initiates fragmentation or de-fragmentation ensuring minimum drops and retransmissions. In a low TTL-based wireless network, the node drops all its energy before actually transferring the data given to it. To address this problem a new routing technique is proposed by which the data from one part is scheduled to reach the destination based on the computed TTL and residual energy. The parameters simulated are throughput, delay, transmit energy and packet delivery ratio.

Keywords: mobile ad-hoc network; MANET; admission control; QoS-aware routing algorithm; contention aware admission control protocol; CACP; adaptive transmission metric.
