A wireless sensor network can work efficiently only if can provide good mobility support. However the existing mobility protocols do not provide the optimal solution due to long handover latency and high packet loss. The term handover or handoff refers to the process of transferring an ongoing call or data session from one channel connected to the core network to another channel this leads to delay. In order to overcome these disadvantages we use location-based mobility support scheme. Mobility support algorithm is used which is based on cluster domain. In this scheme the handover in data link layer (DLL) and network layer are done simultaneously and mobile nodes do not participate in handover process. Hence packet loss due to change in address and node mobility is avoided. Moreover a cluster head's IPV6 address includes location information so there is automatic establishment of routing path to the destination cluster without routing discovery. The main advantage of using location based mobility support is that packet loss and handover cost is reduced. The task of routing data from a source to the sink is a critical issue in wireless sensor networks. To overcome these critical issues we use fuzzy logic to perform role assignment during route establishment and maintenance is proposed. An incremental approach is presented and compared with similar existing routing protocols. Efficient routing approaches provide network load balance to extend network lifetime, efficiency improvements, and data loss avoidance.
