A novel scheme for PMIPv6 based wireless sensor network

Abstract

IP based Wireless Sensor Network (IP-WSN) is gaining tremendous importance because of its broad range of commercial applications in health care, building & home automation, asset management, environmental monitoring, security & safety and industrial automation. A network-based mobility management protocol called Proxy Mobile IPv6 has been standardized by the IETF NETLMM working group, and is starting to pay close attention among the telecommunication and Internet communities. Since host based IP mobility protocol is not feasible for the low power and low cost sensor node, network based mobility management protocol will be well suited for IP-WSN. In this paper we propose SPMIPv6 architecture, respective message formats and analyze the signaling cost and finally evaluate its performance. The result shows that the SPMIPv6 has lower signaling cost and packet delivery cost and it can improve the handover performance of UDP and TCP than the other mobility management protocol. © 2010 Springer-Verlag Berlin Heidelberg.
