Abstract

A mobile ad-hoc network (MANET) is a collection of wireless mobile nodes, which creates a temporary network. Bluetooth is one the of emerging communication standard of MANET. Bluetooth allows communication through a basic network, which is called piconet. A piconet has one master and at most seven active slaves. There can be multiple piconets in Bluetooth network, which is called scatternet. Communication among multiple piconets is achieved trough a common node known as relay. Bluetooth allows synchronize transmission, therefore, packet transmission may always have unreliable links caused by relay node mobility. This degrades the system performance. Devices follow broadcast mechanism to find an alternative route when a link breaks. A large number of broadcasts route requests increase control overheads and consume large amount of power to send and receive control messages. Thus, this paper proposes a Local Route Repairing (LRR) technique for Bluetooth Scatternet to recover lost links efficiently. The proposed LRR achieves several advantages i.e. minimizing the number of control messages, increasing packet delivery rate and reducing network delay. The simulation results show that proposed technique outperforms others, the LRR reduces 20-30% message overhead and increases 15-20% data rate.
