LABC: Local Route Repair using Artificial Bee Colony algorithm in 6LoWPAN network

摘要

The emergence of Internet of Things (IoT), the IEEE 802.15.4 standard introduces wireless sensor network (WSN) from personal area network (PAN) into low power personal area network (LoWPAN). Hence, the use of Internet Protocol (IP) into LoWPAN has broadened new research area known as 6LoWPAN. Nowadays, 6LoWPAN technology is swiftly gaining recognition for its extensive application, ranging from healthcare to environmental monitoring. One of the challenges in 6LoWPAN is the route break often occurs due to node mobility, node failure and channel impairments. There are types of routing protocol that have been proposed to reroute or provide alternative routing to overcome the route break problem. However, the network is burdened of load RREQ the whole network. In this paper, we proposed LABC mechanism in the Local Route Repair using Artificial Bee Colony algorithm in 6LoWPAN network to enhance the routing against route breakage. We compare the packet delivery ratio and end-to-end delay with scalable number of traffic and show that our routing protocol with LABC mechanism significantly reduce average end-to-end delay and increase number of packets delivery.
