Abstract: This paper addresses data aggregation and data packets issues for highly dynamic mobile ad hoc networks and Wireless Sensor Networks thereby leading to a timely and reliable reduction in both communication and energy consumption. But there might be node failures in existing systems and an aggregation framework does not address issues of false subaggregate values due to compromised nodes leading to huge errors in base station computed aggregates when data is transferred through mobile sensor nodes. It cannot also transfer data after nodes fail at the intermediate level. This paper proposes a novel lightweight verification algorithm and Position-based Opportunistic Routing (POR) protocol which reduces node failure and data loss issues. Theoretical analysis and simulation prove that POR and the novel lightweight verification algorithm achieve excellent performance under high node mobility with acceptable overhead. Also the new void handling scheme performs efficiently.
