EMS: Enhanced mobility scheme for controlled and lossy networks

With the emergence of IOT, WSNs have become prevalent for many application areas such as smart city scenario, healthcare, weather monitoring and intelligent transport system etc. Due to their smaller infrastructure and limited energy resources, these networks are considered to be controlled and lossy networks. IP mobility management in such networks playing a crucial role for object tracking or to provide uninterrupted services to mobile users. Existing MIPv6 and its extensions are not suitable for such lossy networks due to the MN´s involvement in heavy signaling, required for HO. Network based protocol; PMIPv6 relieves the MN from heavy signaling overhead and being suggested by many researchers for lossy networks to carry out the mobility. But this protocol still suffers from extra signaling and packet loss and there is a scope for further improvements. This paper presents a novel approach based on PMIPv6 for reducing HO latency and packet loss for some critical applications such as Healthcare, battle field, disaster management, ITS etc. where packet loss is not acceptable. The performance analysis and simulation results show that the proposed scheme is better than the standard PMIPv6.
