Optimised resource management for NEMO mobile networks

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.
