Received Signal Strength Based Wireless Source Localization with Inaccurate Anchor Position

Abstract

Received signal strength(RSS)-based approach of wireless localization is easy to implement at low cost. In practice, exact positions of anchors may not be available. This paper focuses on determining the location of the source in the presence of inexact position of anchors based on RSS directly. This study at first uses Taylor expansion and a min-max approach to get the approximate maximum likelihood estimator of the source coordinates. Then this paper proposes a relaxed semi-definite programming model to circumvent the non-convexity. This paper also proposes a rounding algorithm concerning both the inexact source location and the inaccurate anchor location. Experimental results together with analysis are presented to validate the proposed method

An adaptive social-aware device-to-device communication mechanism for wireless networks

“…The validation of MAMS-D2D scheme was compared with the RSS approach, which is a basic method for selecting the destination in wireless communication system [116]. It is used to compare different schemes since it is easy to set it up and most of the current networks use it to establish the connection based on RSS strength [117]. The RSS approach depends on RSS signal; once the device receives a signal, that means the opposite part (mode or peer) is able to establish the connection.…”

“…This can help in selecting the way of communication based on only RSS value. It is built on the RSS signal re-ceived from the nearby users or BS, which will decide whether or not it is a suitable communication based on this signal [117], [118]. The MAMS-D2D scheme helps in managing the connection through different modes, which have different performance values.…”
