Abstract
IP based Wireless Sensor Networks (IP-WSNs) are being used in healthcare, home automation, industrial control and agricultural monitoring. In most of these applications global addressing of individual IP-WSN nodes and layer-three routing for mobility enabled IP-WSN with special attention to reliability, energy efficiency and end to end delay minimization are a few of the major issues to be addressed. Most of the routing protocols in WSN are based on layer-two approaches. For reliability and end to end communication enhancement the necessity of layer-three routing for IP-WSNs is generating significant attention among the research community, but due to the hurdle of maintaining routing state and other communication overhead, it was not possible to introduce a layer-three routing protocol for IP-WSNs. To address this issue we propose in this paper a global addressing scheme and layer-three based hierarchical routing protocol. The proposed addressing and routing approach focuses on all the above mentioned issues. Simulation results show that the proposed addressing and routing approach significantly enhances the reliability, energy efficiency and end to end delay minimization. We also present architecture, message formats and different routing scenarios in this paper.

Recent technological advances in wireless communication and electronics have developed sensor nodes containing low cost, low power, multifunctional sensor nodes that are small in size and can Sensors 2011, 11 communicate over short distances [1]
We set signaling cost and mobility related cost for the number of IP based sensor nodes and number of hops traverse during the mobility phase in order to evaluate the consequences of our proposed scheme with PMIPv6 and MIPv6

Summary
Recent technological advances in wireless communication and electronics have developed sensor nodes containing low cost, low power, multifunctional sensor nodes that are small in size and can Sensors 2011, 11 communicate over short distances [1]. The tiny sensors are not capable of holding the complete IPv6 addressing since the IEEE 802.15.4 packet size is 127 octets [6,7] and it is not feasible to contain the routing table for the individual IP-WSN sensor node These are the major problems to be addressed in IP-WSNs. These are the major problems to be addressed in IP-WSNs With this in mind, in our previous work [8] we focused on the issue of mobility in IP-WSNs with the intention of developing an energy efficient network-based communication protocol for IP-WSNs. We proposed the Sensor Proxy Mobile IPv6 (SPMIPv6), which is a network-based protocol that provides mobility support to any IPv6 host within a restricted and topologically localized portion of the network, but in our previous paper we did not focus in detail on the addressing and routing issues.
