Energy efficient framework for mobility supported smart IP-WSN

Abstract

Energy efficient Internet Protocol based smart Wireless Sensor Networks (IP-WSN) are gaining tremendous importance because of its broad range of commercial applications in health care, building & home automation, environmental monitoring, security & safety and industrial automation. In all of these applications mobility of sensor node with special attention to energy constraints is an indispensible part. Host based mobility management protocol is inherently unsuitable for energy inefficient IP-WSN. So network-based mobility management protocol can be an alternative to the mobility supported IP-WSN. In this regard, 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. In this paper we propose energy efficient Sensor Network based PMIPv6 protocol called Sensor Proxy Mobile IPv6 (SPMIPv6). We present SPMIPv6 architecture, respective message formats and analyze the energy dissipation and finally evaluate its performance. © 2010 Springer-Verlag Berlin Heidelberg.
