Sammanfattning
In their master thesis “Analysis of IPv6 Neighbour Discovery for Mobile and Wireless Networks” [2] Jeena Rachel John and Hariharasudhan Vigneswaran have analysed the impact of the suggested changes to rfc 4861 found in draft-chakrabarti-nordmark-6man-efficient-nd-06 [1] has on the efficiency regarding multicast messages in a wireless network. <p> The background is that the rfc 4861 is developed for always on stations running on main supply and on a wired LAN. The draft-chakrabarti-nordmark-6man-efficient-nd-06 addresses issues with wireless, battery powered stations. The main consequence of the application of the draft technologies is that the number of multicast messages in an IPv6 LAN is significantly reduced. This of course has an impact on the total energy consumption since most of these multicast messages have to be acted upon by all nodes in a network. The draft advocates for centralising some of the functions carried out by all nodes in the legacy rfc 4861 [3] to a central node. This in turn makes it possible to change from multicast messages to unicast messages only involving the acting end node and the central node. The suggested solution also enables efficient end node sleep mode. <p> We now propose a continuation activity in this area with the following objectives: <ul> <li>Deploy the router developed in the project in e.g. a virtual machine for easy implementation in upcoming test and development environments. <li>Analyse the impact of deploying the draft in a network with end nodes that can go into sleep mode. <li>Analyse the impact that the implementation of the draft has on the central node’s (either if it is a router or an access point) complexity and workload. <li>Expand the analyses done by John and Vigneswaran to include more end nodes and fall-back to rfc 4861. <li>Analyse the impact on total energy consumption in a wireless IoT network. <li>Follow up the impact of the draft has on SLAAC (rfc 4862) [4]. </ul> This project is planned for two master students, one student geared toward software development expert and one whose forte is theoretical and empirical analysis. The project will be located to and performed at EIT in Lund.
