Exploiting the intuition that a less dynamic mute lasts longer, we propose a new metric, the Route FragiI&v Coeficient (RFC), to compare mutes. RFC estimates the rate at which a given mute expands or contracts. Expansion refers to adjacent nodes moving apart, while contraction refers to their moving closer. RFC combines the individual link contraction or expansion behavior to pmsent a unified picture of the mute dynamics. We demonstrate that lower the value of RFC, more static (less fragile) the mute. We then use this metric as a basis for route selection so that route discovery yields mutes that last longer and hence increase throughput while reducing contml overhead. We pmvide a simple distributed mechanism to compute RFC, so that a Route-Request W Q ) packet contains the metric for the path it travened, when it reaches the destination. The Dynamic Source Routing Protocol (DSR). is enhanced with the proposed metric in the NS-2 simulation environment. Simulation msults am provided to demonstrate improvement in thmugbput and reduction in routing pmtocol overhead with increased mobility.","PeriodicalId":122389,"journal":{"name":"The 11th IEEE International Conference on Networks, 2003.

The existing topology control algorithms tend to optimise network power usage by keeping the topology connected but do not take the network application requirements into account. Mission critical applications which require explicit end-to-end bandwidth and delay guarantees may not find enough resources in the network with the existing network topology. We have devised a topology control algorithm for mission critical applications (TCMCA) in wireless ad-hoc networks, which adapts the network topology to improve the available resources for a set of mission critical applications (high priority services) in a network. TCMCA is a source based algorithm where topology control decisions are made on distributed network knowledge. The performance of TCMCA is evaluated for a static wireless network and compared against algorithms such as connect, LINT and full power transmissions. We demonstrate that TCMCA shows better support for mission critical services for varying number of mission critical applications in the network.","PeriodicalId":122389,"journal":{"name":"The 11th IEEE International Conference on Networks, 2003.

In this paper we address the problem of dynamic replica placement to account for users demand variability while optimizing the costs paid by a CDN provider and the overall performance of the distributed replica servers architecture. We formulate the dynamic replica placement problem as a semi Markov decision process accounting for the traffic conditions, the users level of satisfaction, as well as the costs paid to install, maintain or remove a replica from a site. The proposed model applies to general network topologies and considers realistic constraints on network and servers capacity. The optimal strategy derived by means of the decision model provides the ground for designing a centralized heuristic and is used as a benchmark for the heuristic evaluation. Simulation results show that the proposed heuristic has a behavior close to that of the optimal strategy and achieves very good performance in terms of low average distance from a user to the serving replica, low average number of replicas and high probability of being able to serve a request.","PeriodicalId":122389,"journal":{"name":"The 11th IEEE International Conference on Networks, 2003.
