Analysis of congestion control based on Engset loss formula-inspired queue model in wireless networks

Congestion is considered as a potential cause for increased transmission delay when packets are relayed between the source and destination of a mobile ad hoc environment. Thus, balancing the network resources in a distributed manner remains an indispensable consideration in facilitating effective sharing. The efficient sharing of network resources avoids load balancing in mobile nodes, thus preventing their rapid depletion. The proposed method improves the packet delivery rate and throughput of the network and it enables the process of load scheduling based on steady-state equations. Initially, it estimates the minimum queue length based on individual routes, then it sorts the node-disjoint individual routes and finally forwards the packets through the node-disjoint paths identified as reliable. This facilitates improved performances of about 21%, 17% and 25% in terms of packet delivery ratio, throughput and network overhead, compared to the benchmarked baseline queue-based load balancing techniques.
