Abstract-IETF 6LoWPAN working group is engaged in the IPv6 protocol stack research work based on IEEE802.15.4 standard. In this working group, the routing protocol is one of the important research contents. In the 6LoWPAN, HiLow is a wellknown layered routing protocol. This paper puts forward an improved hierarchical routing protocol GHiLow by improving HiLow parent node selection and path restoration strategy. GHiLow improves the parent node selection by increasing the choice of parameters. Simutaneously, it also improves path recovery by analysing different situations to recovery path. Therefore, GHiLow contributes to the ehancement of network performance and the decrease of network energy consumption.

“…An Extended Hierarchical Routing Over 6LoWPAN which extends HiLOW was presented by C.Nam et al in order to have better maintained routing tree [9]. They suggested two additional fields to be added to the existing routing table of HiLOW namely, Neighbour_Replace ]arent (NRP) and Neighbour_Added_Child (NAC).…”

6LoWPAN enables IPv6 to be applied to wireless sensor network and enable end to end communication. One of the 610pwan features is the capability of dynamic assignment of 16 bit short addresses. Using this feature a hierarchical routing protocol was designed. The designed hierarchical routing protocol focuses on the address allocation method and routing mechanism. However the routing protocol doesn't address scenario where there is more than one potential parent node. If the child nodes attaches to the first responding parent when there is more than one potential parent than this could lead to bias or uneven distribution of child node. Bias association could impact the reliability and also shorten the life span of the network. To overcome this problem a mechanism which uses current number of child node of potential parent was suggested. This mechanism displayed weakness when the responding parent node is having different depth or energy level or same number of current child. This paper reviews current hierarchical routing, highlights the issues and suggests a mechanism which avoids a bias routing hierarchical tree set up by taking into account the potential parent node's signal strength, depth and energy level.

“…However, future WSNs consisting of thousands of nodes and these networks may be connected to others via the Internet [1]. Hence, IPv6 over Low power Wireless PAN (6LoWPAN) is defined by Internet Engineering Task Force (IETF) [6] as a technique to apply TCP/IP to WSN [1], [7]. 6LoWPAN provides a WSN node with IP communication capabilities by putting an adaptation layer above the 802.15.4 link layer for the packet fragmentation and reassembly purpose [1], [2], [8].…”

Path recovery mechanism in 6LoWPAN routing

The feature of 6LoWPAN is the capability of the dynamic assignment of 16-bit short addresses. Hierarchical routing (HiLow) algorithm that uses dynamically assigned 16-bit unique short address as its interface identifier has an advantage of memory saving. The 16-bit unique short address is assigned to a 6LoWPAN device during an association operation with a neighbor node which is also called parent node in HiLow. Besides reducing the overhead of maintaining routing table, HiLow also supports for larger scalability. However, previous research did not deal with the path recovery when sensor nodes in HiLow are failed. The node failure may be due to the battery lifetime of the 6LoWPAN device. This kind of failure will cause the expiration of the association event and make the previously assigned 16-bit short address of the child node from the failure parent node become invalid within PAN. In this paper, a new path recovery mechanism so-called step parent node (SPN) algorithm is proposed to conventional HiLow to reassign the valid 16-bit short addresses for the child nodes of the failure parent node and provide the path robustness. The child nodes of the failure parent node will broadcast a step parent node request message (spn_request) to the neighbor nodes. The neighbor node whose child nodes do not exceed the maximum child value will act as a step parent node of the new child nodes. It enhances the reliability of conventional hierarchical routing mechanism.
