ABSTRACT: Wireless Mesh Network is a promising
technology with many challenges yet to be addressed. Novel and efficient
algorithms need to be developed for routing and admission control with the
objective to increase the acceptance ratio of new calls without affecting the
Quality of Service (QoS) of the existing calls and to maintain the QoS level
provided for the mobile calls. In this paper, a novel Markov Decision-based
Admission Control and Routing (MDACR) algorithm is proposed. The MDACR
algorithm finds a near optimal solution using the value iteration method. To
increase the admission rate for both types of calls, a multi-homing admission
and routing algorithm for handoff and new calls is proposed. This algorithm
associates the user with two different access points which is beneficial in a
highly congested network and proposes a new routing metric to assure seamless
handoff in the network. Our proposed algorithm outperforms other algorithms in
the literature in terms of handoff delay, blocking probability, and number of
hard handoff.
