“…Aj j Θ = 2 arcsin(r/ D ) (8) 2 arcsin( / ) Ck k r D Θ = (9) The Euclidean distances and angle of arrivals of reference nodes about the target node are computed as D AB , D CB and AB , CB in equations 10-13. Dynamic switching of reference nodes in PL&T is the assignment of new friendly reference nodes as per requirement when the target node goes out of range from the current reference nodes during localization and tracking.…”

“…Since multi-path fading forces the tracking operation to be conducted at low Eb/No, it is essential to maintain a bounded BER with an average sustained data transmission rate. Using KV transform, it is possible to interleave discrete samples and allow one out of four discrete samples to be corrected exactly [9], it is expected that the tracking accuracy improves significantly. Figure 11-12 illustrates the tracking accuracy improvement when using KV transform that allows sample interleaving over that of without interleaving.…”

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.

ABSTRACT:Over the last decade, a large number of pioneering works have provided foundations for both theory and applications of Wireless Ad hoc Networks (WLAN). As ad hoc technology is becoming the demand of present and future trends that needs for a reliable communication link having minimum BER and power. This review work presents the impact of mobility, and energy efficiency and clustering on optimization of Bit Error Rate (BER) and power as well as on throughput. An analysis review is made on Network coding scheme to optimize BER and throughput. And finally how these factors vary in WLAN is discussed in conclusion.
