Asynchronous multi-channel neighbour discovery for energy optimisation in wireless sensor networks

Abstract

Neighbour discovery is a process that new devices gather the information from their neighbours when they initially join in a wireless sensor network. During this process, energy utilisation efficiency serves as an essential evaluated factor to concern. This paper proposes a novel asynchronous multi-channel neighbour discovery method for the energy-sensitive time division multiple access (TDMA) wireless sensor network. Two aspects are designed to enhance the efficiency of the energy utilisation, including minimising the listening time of the first frame, which is formulated as a linear programming problem and solved using the CPLEX tool, as well as predicting the time slot and position of the beacon frame based on the attained information from the frames and the process dormancy when a beacon frame is impossible to come out. Our simulation results show that the proposed methods effectively reduce the energy consumption during neighbour discovery process in a TDMA-based wireless sensor network.

Performance Analysis of the Industrial Wireless Networks Standard: WIA-PA

“…The paper [13] shows how WIA-PA interconnects with legacy process automation system. The paper [16] proposes a asynchronous multi-channel neighbor discovery method for time division multiple access (TDMA) for WIA-PA. The paper [17] studies a collisionfree multichannel superframe scheduling problem for WIA-PA.…”

“…On the other hand, wireless technologies suffer from the harsh industrial environments since wireless channels are extremely prone to severe damage due to the coexisting interference, fading, and multi-path effect [5,7]. Therefore, guaranteeing the deterministic requirement on the industrial wireless network in spite of the unfriendly wireless channel turns out to be a challenging problem, and industrial wireless networks (IWNs) have aroused a great deal of interest from academia [8][9][10][11][12][13][14][15][16][17][18][19][20][21], industry [22][23][24] as well as standardized organizations [25][26][27]. This paper aims to study IWNs from the standpoint of IWNs standards.…”
