Abstract Mobile IPv4 (RFC 3344) uses the home agent (HA) to a...

Discovering the malicious or vulnerable anchor node is an essential problem in wireless sensor networks (WSNs). In wireless sensor networks, anchor nodes are the nodes that know its current location. Neighbouring nodes or non-anchor nodes calculate its location coordinate (or location reference) with the help of anchor nodes. Ingenuous localization is not possible in the presence of a cheating ...

Malicious anchor nodes will constantly hinder genuine and appropriate localization. Discovering the malicious or vulnerable anchor node is an essential problem in Wireless Sensor Networks (WSNs). In wireless sensor networks, anchor nodes are the nodes that know its current location. Neighbouring nodes or nonanchor nodes calculate its location (or its location reference) with the help of anchor ...

In this paper, a proactive correspondent registration mechanism is proposed for the Proxy Mobile IPv6 (PMIPv6) route optimization between the correspondent node (CN) and the mobile access gateway (MAG) on behalf of the mobile node (MN) in wireless access networks. Two scenarios are considered according to the type of CN. For the proposed mechanism, the proxy home test and the concurrent care-of...

In these days, it is very important to trace a mobile in the vast mobile sensor network. It is mainly for identifying the location of the person who is using that mobile. For this application, the location of the mobile node (mobile) is to be found. This process is known as localization. Out of different types of localization techniques, range-free localization approaches are cost-effective for...

In wireless networks, system survivability is one of the most important issues in providing quality of service (QoS). However, since failure of home agent (HA) or mobile anchor point (MAP) causes service interruption, the Hierarchical Mobile IPv6 (HMIPv6) has only weak survivability. In this paper, we propose Robust Hierarchical Mobile IPv6 (RH-MIPv6), which provides fault tolerance and robustn...

We consider the problem of self-localization by a resource-constrained node within a network given radio signal strength indicator (RSSI) measurements from a set of anchor nodes where the RSSI measurements as well as the anchor position information are subject to perturbation. In order to achieve a computationally efficient estimate for the unknown position, we minimize a weighted sum-square-di...

This paper provides the implementation mechanism of the pmipv6-based partially distributed mobility management (DMM) and performs extensive simulations under various traffic environments for verification and evaluation of the proposed scheme. The simulation results indicated that Mobility Anchor and Access Router (MAAR) could distribute and manage all IP data packet flow between a corresponding...
