Wireless channel resource allocation in WSNs using finger-guessing game

Wireless channel is a limited resource in wireless communication field. In wireless sensor networks (short for WSNs), nodes are commonly deployed with high density. As many nodes are same constructed, this means that there will be only one channel for nodes to carry data. The channel resource competition in WSNs focuses on the time slot allocation. Cognitive radio (short for CR) is a useful method in tackling frequency channel allocation. To efficiently use frequency channel, game theory are introduced in CR and other wireless communication techniques. One of the commonly game is the finger guessing game (short for FGG), which is a traditional game played for fun or punishment in China. FGG consists of two elements: finger numbers and guessing number of the summary of finger numbers. We use FGG as the competition strategy to allocate the channel occupation right in WSNs. Compared with random number competition strategy (short for Rand), FGG strategy reaches the requirement. In this paper, we only simulate the competition process using two strategy mentioned above, and give the comparison of times of having the occupation of every node. From the result we can find that by using FGG strategy as the resource allocation mechanism nodes can reach the similar affection as Rand strategy with more stable and more efficient energy consumption rate.
