On slave-slave bridging with non-acknowledged GTS access in 802.15.4 beacon enabled networks

Abstract

In this paper, we present and analyze non- acknowledged GTS option for interconnection of IEEE 802.15.4 beacon enabled network clusters using ordinary network nodes as bridge nodes. Bridge design involves uplink transmission to the coordinator and downlink transmission to the bridge. Bridge periodically visits source and sink cluster and exchanges data using Guranteed Time Slot (GTS) access. We develop the queuing model for bridging algorithm and present numerically obtained performance results.
