Internet protocol multimedia subsystem (IMS) is an overlaid infrastructure above the packet-switched domain of the universal mobile telecommunication system core network. IMS enables and enhances real-time multimedia mobile services

k -Coterie is a useful concept to solve the distributed k -mutual exclusion problem. The distributed k -mutual exclusion algorithms based on k -coteries have benefits of the high fault-tolerance and the low message cost

This paper is meant to be an illustration of the use of stochastic geometry for analyzing the performance of routing in large wireless ad hoc (mobile or mesh) networks. In classical routing strategies used in such networks, packets are transmitted on a pre-defined route that is usually obtained by a shortest-path routing protocol
