Research on Election of Distributed Wireless Multi-hop Self-organized Network

Abstract

Distributed wireless multi-hop self-organized network has the advantages of flexible networking, powerful extensibility and low costs of operation and maintenance. It has bright prospects in Ultra-Dense Network of 5G (5th Generation Wireless Communication), distributed D2D (Device to Device) communication. An election can avoid excessive signaling overhead caused by repeated reservations and achieve low collision probability of signal transmission, so the election plays an important role in distributed wireless multi-hop self-organized network with its fairness and robustness. However, the study of election has not attracted enough attention, previous studies have focused on election in two-hop range and the performance degradation caused by cumulative interference is never to be considered. Maintaining three-hop neighbors’ information can effectively reduce cumulative interference. In this paper, we research the crucial election parameters, different neighbor maintaining ranges and election efficiency. The numerical simulation results show the impacts of different nodes and election parameters on system performance. Simulation is conducted on based on NS2 platform to verify the impact of election consistency on election performance efficiency. The optimization strategies of election parameters and election consistency issues are further obtained.
