A novel load balancing technique for proactive energy loss mitigation in ubiquitous networks

Any ad hoc ubiquitous network should be capable of taking proactive measures for smooth reconfiguration in the event of energy loss and a failure to key network Parent Nodes (PN). The overall objective of reconfiguration is to keep the network operating effectively for a prescribed time frame. The load profiles of PNs can be used to define its current state as well as to predict potential failures caused by energy loss due to high loads on particular PNs. This paper presents a new technique utilising historical load profile information about each PN to improve the estimate accuracy of its remaining lifetime before failure. A novel load balancing model is introduced that maintains PNs in a state whereby the time- to-live requirement is met by the PNs comprising the backbone of the network. Results prove that the proposed methodologies achieve the reconfiguration objectives as well as maintaining QoS, especially in high density ad hoc networks
