摘 要: 对现有基于p-坚持随机发送概率的邻居发现算法进行分析,结果表明:最优普适发送概率不具实践价值,经分析得出,在单个时隙上进行“多重发送”的方法基本上不能改善邻居发现概率。在此基础上提出了相应的改进方法,其分析及仿真结果表明:改进算法能够有效地改进原算法的性能。
关 键 词: 通信与信息系统;邻居发现;p-坚持;冲突解析

Abstract: This paper analyzes existing neighbor discovery algorithm based upon p-persistent random announcement strategy. Simulation results have shown that no universal optimal transmission probability p as stated in current literature exists. And the paper also shows that p-persistent multiple announcement proposed by current literature can not improve neighbor discovery performance since it is equivalent to that of single announcement. Thus, the paper proposes a modified p-persistent random announcement strategy for neighbor discovery. Analysis and simulation results show that the proposed method can effectively improve the performance of the original algorithm.
Key words: communication and information system; neighbor discovery; p-persistent; collision resolution
