Agent based micro-mobility protocols such as Hierarchical Mobile IPv6 deploy special IPv6 nodes called Mobility Agents that act as an anchor point between the Mobile Node and the Home Agent providing localized mobility support. The location and the number of MAs deployed within the network can affect the performance of the protocol. This paper deals with the problem of Mobility Agent (MA) locat...

Location privacy protection in VANETs considers preserving two types of information: the locations and identifications of users. However, existing solutions which either replace identifications by pseudonyms or hide locations in areas cannot be directly applied to geographic routing protocols since they degrade network performance. To address this issue, we proposed a location-preserved content...

We present a general framework for modeling routing problems based on formulating them as a traditional location problem called the Capacitated Concentrator Location Problem. We apply this framework to two classical routing problems: the Capacitated Vehicle Routing Problem and Inventory-Routing Problem. In the former case, the heuristic is proven to be asymptotically optimal for any distributio...

Previous research has illustrated that locationbased routing protocols improve the effectiveness of mobile ad hoc network (MANET) routing. The goal of a location server, which may be used in conjunction with a locationbased routing protocol, is to provide accurate location information on the mobile nodes in the network. In this paper, we implement a location server for a MANET using our Legend ...

In mobile ad hoc network there are several routing algorithms, which utilize topology information to make routing decisions at each node. aim of this paper is to utilize position information to provide more reliable as well as efficient routing for certain applications. Thus extensions to existing position based routing algorithm have been described to work more efficiently even in cases where ...

Routing in Mobile Ad-Hoc Network (MANET) is a crucial task due to highly dynamic network environment. In latest years, several routing protocols have been implemented. In recent developments, position-based routing protocols exhibit better scalability performance and robustness against frequent topological changes such as, Location-Aided Routing (LAR) protocol. In this paper, developments of pe...

Node Location information may reduce the overall communication overhead for packet forwarding in Mobile Ad-Hoc Networks (MANETs). This paper proposes a novel Geographic Location Aware Adaptive Routing (GLAAR) protocol to reduce the computation and communication requirement for selection of next node (hop) for packet forwarding. Proposed protocol fetches the node location information using GPS a...

We present an information theoretic analysis of the minimum routing overhead incurred for reliable routing of packets using location-based routing. We formulate the minimum routing overhead problem as a rate-distortion problem and derive a lower bound on the minimum routing overhead incurred. We also characterize the deficit in transport capacity caused by the routing overheads. It is observed ...

Bluetooth is a most promising technology for the wireless personal area networks and its specification describes how to build a piconet. Though the construction of scatternet from the piconets is left out in the specification, some of the existing solutions discuss the scatternet formation issues and routing schemes. Routing in a scatternet, that has more number of hops and relay nodes increase...
