In a wireless sensor network (WSN), the energy of nodes is limited and cannot be charged. Hence, it is necessary to reduce energy consumption. Both the transmission power of nodes and the interference among nodes influence energy consumption. In this paper, we design a power control and channel allocation game model with low energy consumption (PCCAGM). This model contains transmission power, node interference, and residual energy. Besides, the interaction between power and channel is considered. The Nash equilibrium has been proved to exist. Based on this model, a power control and channel allocation optimization algorithm with low energy consumption (PCCAA) is proposed. Theoretical analysis shows that PCCAA can converge to the Pareto Optimal. Simulation results demonstrate that this algorithm can reduce transmission power and interference effectively. Therefore, this algorithm can reduce energy consumption and prolong the network lifetime.

“…In fact, these dynamic channel switches may cause data transmission delay and frequent control message exchange may consume more energy. Daniela et al [28] present the implementation of a CA algorithm in a field-programmable gate array, which assigns channels to sensor nodes based on the interference and noise levels experimented in the network. Barcelo et al [29] enhance Routing protocol for low-power and lossy networks to obtain a joint routing, transmission power control and channel allocation solution for real-life WSNs while Jinbao et al [30] develop a polynomial time heuristic channel optimal assignment algorithm jointing routing, scheduling, CA and power control.…”

For the feature of zero delay in continuous relay transmission, wireless sensor networks (WSNs) supporting multiple communication interfaces is much suitable for data collection and transmission backbone network of coal mine safety monitor and control system which has high demand of reliability in real-time data transmission. Based on in-depth analysis of the existing distributed channel allocation algorithms, this study proposes an innovative fast distributed channel allocation scheme based on largest edges of network topology (CALENT) with the combination of wireless network architecture features. By comparing with existing distributed channel allocation dis-link algorithm, CALENT has better performance in co-channel interference index and convergence velocity.
