We compare two representative methods, multilateration and MDS-MAP, and study some of their key issues that affect the performance. First, we study the various optimization techniques and the effect of anchor selection for multilateration and the effects of the sizes of local maps and the refinement techniques for MDS-MAP. Secondly, we investigate the error property of localization by deriving the Cramer-Rao bound for different topologies and compare the bounds with the results of the two methods on different anchor placements. Previous results suggest that anchors should be placed on the perimeter of the network to get more accurate solutions. Our results show that MDS-MAP tolerates \"ill placement\" of anchors much better than multilateration. Finally, we compare the performance of the two methods through extensive simulation and identify the situations when one method is better than the other.","PeriodicalId":150940,"journal":{"name":"2004 IEEE International Conference on Mobile Ad-hoc and Sensor Systems (IEEE Cat.

First, GPSR is designed under the assumption of symmetric links (i.e., bidirectional reachability) which is not realistic for many practical sensor networks. Second, in sensor networks, packet destinations are often marked with locations instead of identifiers like IP address and therefore packets are routed to the home node which is the node geographically closest to the destined location. GPSR is not efficient in identifying the home node when the target location is outside the exterior perimeter of the sensor network. Third, due to the dynamic nature of sensor networks, maintaining data consistency, that is, data retrieved from the home node for a location should be consistent with the data sent to the same location, becomes a challenge when home nodes change. We propose on-demand GPSR (OD-GPSR), a data driven geographical routing protocol customized for sensor networks with solutions to the above three problems. Simulation results show that OD-GPSR performs well in terms of energy efficiency and packet delivery rate at the cost of a little more packet delivery delay.","PeriodicalId":150940,"journal":{"name":"2004 IEEE International Conference on Mobile Ad-hoc and Sensor Systems (IEEE Cat.

A location service is therefore critical to location-based routing, the scalability of which hinges largely on the overheads of such a service. Although several location service schemes have been proposed, most of them focus only on one or two aspects of scalability in their performance evaluations, and a comprehensive comparative study is missing. We first explore the design space of location services and present a taxonomy of existing schemes. We then propose HIGH-GRADE, a new location service scheme that employs a multilevel hierarchical location server structure and a multi-grained location information organization. We develop a uniform theoretical framework to analyze HIGH-GRADE and four other existing schemes in terms of three metrics: location maintenance cost, location query cost, and storage requirement cost. We show that the design of a location service scheme involves tradeoffs among all three of these kinds of overhead. Further, in our theoretical analysis and simulation experiments, HIGH-GRADE demonstrates superior scalability, especially when a localized data traffic pattern is assumed.","PeriodicalId":150940,"journal":{"name":"2004 IEEE International Conference on Mobile Ad-hoc and Sensor Systems (IEEE Cat.

Hence, the organization of a MAC layer is the primary goal during and immediately after the deployment of such networks. Computing a good initial clustering facilitates this task and is therefore a vital part of the initialization process. A clustering based on a maximal independent set provides several highly desirable properties. Besides yielding a dominating set of good quality, such a clustering avoids interference between clusterheads, thus allowing efficient communication. We propose a novel algorithm that works under a model capturing the characteristics of the initialization phase of unstructured radio networks, i.e., asynchronous wake-up, scarce knowledge about the topology of the network graph, no collision detection, and the hidden terminal problem. We show that even under these hard conditions, the algorithm computes a maximal independent set in polylogarithmic time.","PeriodicalId":150940,"journal":{"name":"2004 IEEE International Conference on Mobile Ad-hoc and Sensor Systems (IEEE Cat.

The integration enriches the application range of ad hoc networks. Earlier approaches for the integrated networks either provided only unidirectional global connectivity for ad hoc hosts or caused high overhead and delay for providing full bi-directional connections. In this paper, an enhanced DSDV (EDSDV) protocol is proposed for ad hoc networks. The EDSDV protocol is integrated with Mobile IP to provide full bi-directional Internet connectivity for ad hoc network hosts. This approach has smaller overhead for full bi-directional connectivity and also shorter average packet delay compared to other integration approaches.","PeriodicalId":150940,"journal":{"name":"2004 IEEE International Conference on Mobile Ad-hoc and Sensor Systems (IEEE Cat.

If MANET nodes have sensing capabilities, they can capture and communicate the state of their surroundings, including environmental conditions or objects in their proximity. If the sensed state information is propagated to a database to build a consistent model of the real world, a variety of promising context-aware applications becomes possible. We introduce a novel consistency concept that preserves the chronological ordering of sensed state transition events. Based on this concept, we propose a data replication algorithm for MANETs that guarantees the consistency concept without relying on synchronized clocks and show its correctness. Our simulation experiments show that replicated copies are updated regularly even if the network load in the system is high.","PeriodicalId":150940,"journal":{"name":"2004 IEEE International Conference on Mobile Ad-hoc and Sensor Systems (IEEE Cat.

Although caching frequently accessed data items in mobile terminals (MTs) improves the communication performance in an IMANET, it brings a critical design issue when data items are updated. We analyze several push and pull-based cache invalidation strategies for IMANETS. A global positioning system (GPS) based connectivity estimation (GPSCE) scheme is first proposed to assess the connectivity of an MT for supporting any cache invalidation mechanism. Then, we propose a pull-based approach, called aggregate cache based on demand (ACOD) scheme, to find the queried data items efficiently. In addition, we modify two push-based cache invalidation strategies, proposed for cellular networks, to work in IMANETs. These are a modified timestamp (MTS) scheme, and an MTS with updated invalidation report (MTS+UIR) scheme. Simulation results indicate that our proposed strategy provides high throughput, low query latency, and low communication overhead, and thus, is a viable approach for implementation in IMANETS.","PeriodicalId":150940,"journal":{"name":"2004 IEEE International Conference on Mobile Ad-hoc and Sensor Systems (IEEE Cat.
