【摘要】 本文针对网状结构的无线物联网中的多跳切换场景,提出了一种基于网络编码的多中继协作切换机制MRH.MRH机制中采用了基于势能场的路由探测算法,通过中继协作的方式,将移动终端同时注册到多个漫游域上.配合网络编码,MRH机制使移动终端建立了到多个无线物联网接入点之间的灵活、可靠的切换连接,实现了在多个无线物联网间的平滑切换.更多还原

【Abstract】 In this paper,we propose a network coding based multi-relay cooperative handover mechanism MRH,for multi-hop handover scenario in wireless internet of things.MRH adopts a route detection algorithm based on potential energy field.One mobile terminal can register on multiple roaming area through intermediate cooperation.Based on network coding,mobile terminal establishes reliable,flexible handover connections with multiple network access points,then smooth handover between multiple internet of things can be realized.更多还原
