Restore Partitioning in MANETs with Dynamically Deployed Helping Hosts - Message Cabs (MCabs)

摘要

Helping hosts are intensively used in various schemes to restore partitioned Mobile Ad Hoc Networks (MANETs). Most of the existing schemes offers only deterministic helping host deployment, and are thus not able to deal with fluctuating network traffic, which is a practical condition in many MANET applications. In this paper, we argue that dynamic helping hosts, with deployment that response to the changes in the traffic demand of the network, may overcome this drawback and reduce the message delay in the networks. To demonstrate the effectiveness of this observation, we propose a new helping host scheme namely the Message Cab (MCab) scheme for partition restoration in MANETs, and validate the performance through simulations.
