Intra-Collision-Free Wireless Multihop Transmission Method based on SIR Wireless Communication Model

Abstract (in Japanese) (See Japanese page) 
(in English) In wireless multihop networks, a sequence of data messages are transmitted along a predetermined wireless multihop transmission route.
Collisions among wireless transmission signals from the intermediate wireless nodes cause longer end-to-end transmission delay of the data messages.
Hence, avoidance and/or reducition of collisions between 2-hop neighbour intermediate nodes due to the hidden terminal problem is required.
It is impossible for wireless multihop transmissions based on the unit disk model in which wireless transmission ranges of intermediate wireless nodes are always the same to avoid contentions for less retransmissions due to collision avoidance.
For the more general disk model wireless transmissions in which each intermediate wireless node determines its wireless signal transmission range, RH2SWL is one of the solutions.
Here, a wireless multihop transmission route consists of a sequence of wireless communicaiton links whose length becomes shorter in hop-by-hop manner.
A wireless transmission range of a previous-hop intermediate wireless node contains an intermediate wireless node though it is not included in a wireless transmission range of its next-hop intermediate wireless node.
Thus, at the intermediate wireless node there no collisions between its previoud-hop and next-hop intermediate wireless nodes.
However, in a wide-area wireless multihop network where a wireless multihop transmission route tends to be longer, i.e. its hop count is larger, the route detection ratio tends to be lower since it becomes difficult for each intermediate wireless node to detect its next-hop node with its shorter wireless signal transmission range to configure a sequence of hop-by-hop shorter wireless communicaiton links.
In order to solve this problem, this paper proposes a novel routing method for a wide-area wireless multihop networks based on the SIR model.
The proposed routing method configures a wireless multihop transmission route where each intermediate wireless node receives wireless signal from its previous-hop intermediate wireless node without collisions with that from its next-hop wireless node, i.e., no collision wireless multihop transmissions due to the hidden terminal problem is realized, though such a strict restriction is no required to be satisfied.
The proposed routing method is expected to improve the route detection ratio and to porvide much more highly available wireless multihop networks than the conventional methods.
