摘要
The mobility of nodes with a purpose called as robotic-mobility is used for replenishing energy to strategic military applications. Connected dominating set(CDS) provides a virtual backbone in adhoc network. Assuming a CDS based backbone in place, we give a technique of maintaining the location of mobile node for a given topology setting. We show that using a weighted CDS reduces the maintenance of location updates for mobile node. The complexity of our mobile-node maintanence algorithm is at most O(d. log d) where d is number of boundary crossings in the single node's movement. The simulation shows that our weighted CDS method for mobile-nodes achieve 40% reduction in location maintenance using to shortest-hop path in CDS.
