Link prediction for identifying link failure using cross layer approach

Mobile Adhoc networks have been a popular research topic in the last few years due to their many applications in the civil and military fields. The standard IEEE 802.11 and ordinary routing protocols are preferred for applications where the reliable and quick delivery of data is important. The goal of the work was to minimize packets drops by switching to alternate path even before links fail with the help of link prediction and to reduce energy consumption in an Adhoc network while maximizing the network throughput. The cross layer design for power control and link prediction in mobile Adhoc networks (DPCPLP) that provides a combined solution for power conservation as well as link availability. The received signal strength of the packets is used as cross layer interaction parameter. This combines the effect of optimum transmit power and received signal strength based link availability estimation with AODV routing protocol using cross layer approach. This method proposes to use optimum transmit power for transmitting the packets to a neighboring node to increase the battery life of Adhoc nodes and received signal strength based link prediction to increase the availability of the links.
