Performance Modeling of Blocking Probability in Multihop Wireless Networks

Ad-hoc network communication requires efficient routing protocols to overcome the problems associated with unpredictable and dynamically changing topologies, which are mostly triggered by nodes mobility and non-existence of base stations and central controllers. We propose a performance evaluation model for blocking probability of multihop calls in ideal macrocell environment conditions using the Markovian process. The proposed model which computes the end-to-end blocking probability and establishes a relation between blocking probability and the system’s throughput is implemented through extensive computer simulation. Simulation results allow for an accurate evaluation of the network performance in the presence of impairments caused by call blocking.
