Zone Repartitioning: A Load‐Balancing Mechanism for Data‐Centric Storage Systems

Mu‐Huan Chiang, Gregory T. Byrd

Data‐centric storage is an efficient scheme to store and retrieve event data in sensor networks, but with the multi‐hop routing nature of sensor networks, the communication cost…

DRKH: A Power Efficient Encryption Protocol for Wireless Devices

Ahmad M. Kholaif, Magda B. Fayek, Hussein S. Eissa, Hoda A. Baraka

In this paper, we present Dynamic Re‐keying with Key Hopping (DRKH) encryption protocol that uses RC4 encryption technique to ensure a strong security level with the advantage of…

Autonomous Clustering and Message Passing Protocol for Energy Efficiency in Wireless Sensor Networks

Jenhui Chen, Chien‐Chun Joe Chou

Wireless sensor networks consist of a large number of nodes with limited battery power and sensing components, which can be used for sensing specified events and gather wanted or…

A Fully Distributed Multi‐Channel MAC Protocol for Ad Hoc Networks Based on Location Information

Shih‐Lin Wu, Jang‐Ping Sheu, Chung‐Chao Lee

This paper proposes a distributed multi‐channel MAC protocol which is an extension of our early work GRID [1]. GRID is characterized by the following features: (i) it integrates a…

GRAViTy: Geographic Routing around Voids in Sensor Networks

Tassos Dimitriou, Ioannis Krontiris

Nodes in sensor networks do not have enough topology information to make efficient routing decisions. To relay messages through intermediate sensors, geographic routing has been…

Label Routing Protocol: A New Cross‐Layer Protocol for Multi‐Hop Ad Hoc Wireless Networks

Yu Wang, Jie Wu

Compared to the traditional wireless network, the multi‐hop ad hoc wireless network is self‐configurable, dynamic, and distributed. During the past few years, many routing…

Multi‐Hop Cellular IP: A New Approach to Heterogeneous Wireless Networks

Bin Xie, Anup Kumar, Dave Cavalcanti, Dharma P. Agrawal

This paper proposes a new Heterogeneous Multi‐hop Cellular IP (MCIP) network that integrates multi‐hop communication with Cellular IP. MCIP increases the coverage of the wireless…

An RPC Design for Wireless Sensor Networks

Terry D. May, Shaun H. Dunning, George A. Dowding, Jason O. Hallstrom

Wireless sensor networks (WSNs) will profoundly influence the ubiquitous computing landscape. Their utility derives not from the computational capabilities of any single sensor…

SDREAM: A Super‐Small Distributed REAL‐Time Microkernel Dedicated to Wireless Sensors

Haiying Zhou, Kun Mean Hou, Christophe De Vaulx

Traditional embedded operation systems are resource consuming multitask, thus they are not adapted for smart wireless sensors. This paper presents a super‐small distributed…
