Dynamic PL&T using Two Reference Nodes Equipped with Steered Directional Antenna for Significant PL&T Accuracy

Abstract

Dynamic Position Location and Tracking (PL&T) is proposed deploying the integrated approach of zone finding and triangulation using two friendly nodes equipped with Steered Directional Antenna (DA) in Mobile Ad hoc Networks (MANET).This approach allows the system to use only two references instead of a typical 3 references for a straight triangulation. Moreover, the performance of the proposed algorithm with references using directional antennas shows significant improvement over triangulation using references with Omnidirectional antennas as the beam power is concentrated. However, dynamic switching of reference nodes is frequently required as the target moves outside the predicted zone. This paper presents a better tracking accuracy in using proposed dynamic PL&T as compared to other PL&T techniques. The multipath fading is also addressed with the use of KV transform coding technique which uses forward error correction and sample interleaving achieves greater than 90% tracking accuracy with BERs of 10 -6 or better.

Highly Reliable Multi-Service Provisioning using Sequential Prediction of Zone and PL&T of Nodes in Mobile Networks

“…Basically the triangles will be formed between any two reference nodes and the target node. Triangulation based PL&T has drawback of the cumulative error during localization and tracking as nodes are continuously tracked at different locations [3]. To get good geometry, we have to carefully place the reference nodes such that there is no angle less than 30 degrees or greater than 150 degrees on the triangles.…”

“…To identify the PL&T of a target, different PL&T techniques have been developed using friendly reference nodes: single reference node based PL&T [2], two reference nodes based PL&T [3], three reference nodes based Triangulation [4], and four reference nodes based multilateration methods and multiple targets' PL&T [4] where each of above methods is analysed by developing theoretical models for PL&T precision. Some of the important PL&T methods are reviewed through literature are described below.…”

“…In [11], cluster head uses the Position Location and Tracking (PL&T) system [12] of all the nodes within the cluster and develops a snap shot of the cluster. The CH periodically broadcast the snap shots to ensure nodes know as and when PL&Ts of nodes have changed.…”
