Abstract

Purpose

–

The purpose of this paper is to propose a distributed protocol to build a logical coordinate system based on the hop counts of each node to four selected landmarks, and the real location information is not needed.

Design/methodology/approach

–

The designed protocol uses the sink node as one of the landmarks and then selects three other sensor nodes near the corners of the sensor network as landmarks.

Findings

–

The simulation results show that the proposed protocol has the superior performance in packet delivery ratio, average hop counts among nodes, and communication overhead to previous works.

Originality/value

–

This paper presents a distributed protocol to build a logical coordinate system based on hop counts to landmarks.
