IP-based Wireless Sensor Networks (IP-WSNs) are gaining importance for their broad range of applications in health care, home automation, environmental monitoring, industrial control, vehicle telematics, and agricultural monitoring. In all these applications, a fundamental issue is the mobility in the sensor network, particularly with regards to energy efficiency. Because of the energy inefficiency of network-based mobility management protocols, they can be supported via IP-WSNs. In this paper,

Based on [8, 20] , we present its network architecture and evaluate its performance by considering the signaling and mobility cost. Our analysis shows that the proposed scheme reduces the signaling cost, total cost, and mobility cost. With respect to the number of IP-WSN nodes, the proposed scheme reduces the signaling cost by 7% and the total cost by 3%.With respect to the number of hops, the proposed scheme reduces the signaling cost by 6.9%, the total cost by 2.5%, and the mobility cost by 1.5%. With respect to the number of IP-WSN nodes, the proposed scheme reduces the mobility cost by 1.6%. Recent advancements in micro-electro-mechanical and wireless communication systems have enabled the development of low cost, low power, and multifunctional sensor networks (SNs) that are small in size and can communicate over short distances [1, 2] . A sensor network is a special type of communication network that is composed of a large number of tiny SNs; these SNs are densely deployed either inside the phenomenon or very close to it [1]. The sensors are generally equipped with data processing and communication capabilities. Accordingly, the sensing circuitry senses the environment surrounding the sensor and transforms that information into an electric signal. It then sends this signal, usually via radio transmitter, to the sink node either directly or through other SNs. The IPv6 defines the manner in which IPv6 communication is to be carried out over the IEEE 802.15.4 interface via the low power wireless personal area network (6LoWPAN) working group of the Internet Engineering Task Force (IETF) [3, 4] . Although 6LoWPAN helps to make the wide implementation of IP-WSNs a reality and its end-to-end communication to the external world feasible, excessive tunneling through the air results in increased signaling costs for SNs, making these pursuits difficult. Yet, excessive signaling costs can be limited through the application of IP-WSNs [5] . Moreover, most communication protocols are host-based nowadays, and individual nodes need to participate in mobility related signaling, which is virtually impossible for IP-WSN. Thus, PMIPv6 [9] is a network-based protocol that provides mobility support to any IPv6 host within a restricted and topologically-localized portion of the network, without requiring the host to participate in any mobility-related signaling.
