Optimised resource management for NEMO mobile networks
I. Ben Hamida, Lila Boukhatem · 2006
In NEMO (NEwork Mobility) context, service degradation or forced call termination may occur because of frequent handoffs. In this paper, we propose and evaluate a new scheme for quality of service guaranty support. This scheme called Time-based Bandwidth Reservation (TBR) is adapted to NEMO specifications and consists in sending reservation requests to the neighboring cells based on real-time measures of mobile networks. The goal of our scheme is to adjust the amount of time for which bandwidth has to be allocated and reserved in a cell. Detailed performance results of TBR scheme and comparison with guard channel scheme are presented. The simulation results show that the proposed TBR scheme can efficiently improve the flow dropping probability.
