Hybrid Distributed Stochastic Addressing Scheme for ZigBee/IEEE 802.15.4 Wireless Sensor Networks

Abstract

This paper proposes hybrid distributed stochastic addressing (HDSA), which combines the advantages of distributed addressing and stochastic addressing, to solve the problems encountered when constructing a network in a ZigBee‐based wireless sensor network. HDSA can assign all the addresses for ZigBee beyond the limit of addresses assigned by the existing distributed address assignment mechanism. Thus, it can make the network scalable and can also utilize the advantages of tree routing. The simulation results reveal that HDSA has better addressing performance than distributed addressing and better routing performance than other on‐demand routing methods.

An Adaptive Superframe Duration Allocation Algorithm for Resource-Efficient Beacon Scheduling

“…Some researchers [2][3][4][5][6][7][8][9] have focused on preventing beacon collisions among coordinators or routers in a tree network. Two different proposals by TG4b [2] have dealt with beacon collision and interference problems among different coordinators.…”

“…For a specific sensor application, such as target monitoring, an adaptive beacon interval method, with respect to varying the detection level of the target, has been proposed by Chen et al [8]. In addition, Kim and Yoon [9] proposed a tree-routing protocol based on a hybrid scheme combining distributed and stochastic addressing methods. Although these studies address a beacon-collision problem in a multi-hop network, most of them have focused only on a tree architecture in which failures of some point can make a partial or entire network lose connectivity to its root.…”

“…However, in multi-hop networks, beacon packets from different nodes have a high collision probability, and a beacon collision problem is therefore considered to be one of the most significant challenges in designing a multi-hop network that is based on IEEE802. 15.4. Over the past few years, several studies [2][3][4][5][6][7][8][9][10][11][12][13] have been conducted on improving the energy efficiency and reliability in multi-hop networks that are based on IEEE802.15.4. Most of them have mainly focused on solving beacon collision problems.…”

“…Most of them have mainly focused on solving beacon collision problems. More specifically, the authors of [2][3][4][5][6][7][8][9] proposed the use of beacon scheduling algorithms and protocols for multi-hop tree networks that are based on ZigBee [14]. While these studies addressed the beacon-collision problem in a multi-hop network, most of them have only focused on the tree architecture in which some failures can make a partial or entire network lose connectivity to its root.…”

The relay scheme over MAC for data transmission performance in railway wireless sensor network

“…As WSNs are expected to assume a greater role in everyday life, ZigBee, the representative communication network protocol of WSN, has become an active research subject [6]. ZigBee positioning is considered a promising open standard that is used with low data rates and low power in costeffective wireless network products [7].…”
