In contrast to existing HAR mechanisms (Thepvilojanapong et al., 2005), the proposed BHAR is able to prolong network lifetime as it constructs hierarchical trees and repairs routes faster. BHAR is unique in letting sinks and sources initialise the construction of a hierarchical tree. Whenever a node knows its own parent and neighbour nodes, it can join a tree, exchan
