Dynamic Load Balancing through Backup Relay in Bluetooth Scatternet

A mobile ad-hoc network (MANET) is a collection of wireless
mobile nodes, which creates an infrastructure less temporary
network. Bluetooth is a short range, low-cost, and low power
wireless technology. Bluetooth allows communication among
electronic devices through a basic network called piconet. One device controls piconet, which is called master and other act as slaves. Multiple piconets may exist in Bluetooth network known as scatternet. The connection among different piconets is provided through a common node known as relay. Relay is connected with more then one master with different hopping pattern, relay node forwards data among different piconets. The degree (number of connection) of relay has a serious impact on network performance. The larger degree relay increases packet loss rate and transmission delay, and it has to switches among different
piconets that also increase scheduling overhead. This paper
considers the problem of designing an effective Dynamic Load
Balancing (DLB) technique to share traffic load through Backup Relay (BR). The proposed technique avoids bottleneck and reduces transmission delay. The simulation is also conducted to show the supremacy of proposed work by using UCBR that is an extension of NS-2. Proposed technique reduces packet loss moreover it increases throughput and network lifetime.
