Originator Recognition (or) Path Recovery Mechanism for Load-Based Routing Protocol

Abstract

6LoWPAN has become a new technology to provide the internet connectivity to the traditional WSN. The introduction of 6LoWPAN adaptation layer enables the smooth delivery of packet from network layer to MAC layer. In this paper, the LOAD-based routing protocol with the proposed originator recognition (OR) path recovery mechanism is introduced. The proposed OR path recovery mechanism modifies the IETF conceptual LOAD protocol message by inserting an identity key in the generated RERR message. The identity key is then used by the originator of a failed data packet to initialize path recovery during the link failure. The developed OR-LOAD has examined under the 6LoWPAN environment in Qualnet simulator. Its performance is evaluated and compared to AODV in terms of packet delivery ratio and throughput.

6RLR-ABC: 6LOWPAN Routing Protocol with Local Repair using Bio Inspired Artificial Bee Colony

“…However, if the receiving node of RERR message is not the source of the failed data packet, the RERR header field is discarded. Then, the RERR is forwarded to upstream node until it reaches the originator of the data packets [15]. This work can increase network overhead by having three states.…”

“…Link break is one of the main challenges that the routing protocols experience [13][14][15] [36]. It suspends the traffic flow or totally stops it sometimes.…”

The effects of route break position for fragmented and unfragmented packets in 6LoWPAN network

“…Node 3 receives the RREQ and responds with local RREP to node 1 to establish local connection in the same path to the destination. The process of local RREQ and RREP between node 1 and node 3 by abandoning node 2 to resume the data transfer between the source and the destination called the repairing the route break [8]. This introduced mechanism is designed to solve route breaks in multi-hop environment.…”
