Markov Chain for Multihop WSN

GOAL :

1. propose a Markov chain-based analytical framework for modeling the behavior of the medium access control (MAC) protocol in IEEE 802.15.4 multihop wireless sensor networks
2. Extend the framework proposed in “I. Ramachandran, A. K. Das, and S. Roy, “Analysis of the contention access period of IEEE 802.15.4 MAC,” ACM Trans. Sensor Networks, vol. 3, no. 1, 29 pages” to 2-hop network scenario.

ZigBee Wireless Networking Book

Although my research focus on IEEE 802.15.4, this book is a good reference to understand ZigBee.

This book is designed to be read from cover-to-cover, tutorial style. Each chapter introduces concepts that are used in later chapters. However, the reader is encouraged to skip ahead if the concepts of any section are already familiar. To keep the reader oriented in each section, some overlap is necessary.

While it is not required, it is helpful to have the ZigBee and IEEE 802.15.4 specifications available when reading this book. I’ll sometimes refer to a section or a concept in those specifications for further reading.

To obtain the ZigBee specification, go to http://www.zigbee.org and click on “Download the Specification.” It is free, and comes in PDF format.

Go to http://standards.ieee.org/getieee802/802.15.html and select “IEEE 802.15.2-2003” to obtain the 802.15.4 standard in PDF format. There is a new draft standard, IEEE 802.15.2-2006, but ZigBee does not currently use that specification.

Beacon Order Adaptation

GOAL :

1. Propose an individual beacon order adaptation (IBOA) which can individually adapt the beacon interval and duty cycle of each node at the same time to the node’s individual performance requirements

Adaptive Backoff Exponent

GOAL :

1. Propose and efficient management of BEs based on the decision criterion
2. Present a brief study of the CSMA-CA mechanism used in IEEE 802.15.4, with emphasis on the improper BE distribution which result in frequent packet collisions and a loss in systems performance.
3. propose algorithm called the Adaptive Backoff Exponent (ABE) which reduce the probability of devices choosing identical number of backoff periods

Superframe Adaptation

GOAL:
1). Propose an enhancement of IEEE 802.15.4 beacon-enabled mode which adaptively adjusts the active period based on the traffic information

NOTE:
1). Despite its design support for low duty-cycle operation, the fixed superframe size in Beacon-enabled mode limits its capabilities due to two contrasting goals : energy efficiency and higher data troughput

LEACH

GOAL:
1). Proposed LEACH (Low-Energy Adaptative Clustering Hierarchy)
2). Comparing LEACH with the conventional protocols of direct transmission, minimum-transmission-energy, multi-hop routing, and static clustering

Beacon Scheduling Mechanism

Goal :

1). Proposed two collision-free beacon frame scheduling schemes
2). Build a synchronized multi-hop cluster-tree network

3). Schedule the generation time offsets of beacon frames issued from different coordinators to completely avoid beacon frame collisions with each other and with data frames
4). The author proposed a mechanism to implement the Time Division Approach and Beacon-Only Period Approach that proposed by the Task Group 15.4b
NOTE:

1. The most important technical features of Zigbee are to provide low power consumption and real-time guarantees.
2. The beacon-enabled mode offers real-time guarantees by means of the GTS mechanism.
