A hybrid power‐saving protocol by dual‐channel and dual‐transmission‐range clustering for IEEE 802.11‐based MANETs

Jehn‐Ruey Jiang, Chau‐Yuan Yang, Ting‐Yao Chiou, Shing‐Tsaan Huang

There are two types of medium access control (MAC) layer power‐saving (PS) protocols for IEEE 802.11‐based mobile ad hoc networks: synchronous and asynchronous ones. This paper…

Data rate estimation algorithm for IEEE 802.11e HCCA scheduler

Jing‐Rong Hsieh, Tsern‐Huei Lee

As the real‐time applications used in today's wireless network grow, some schemes are required to provide better quality of services. From the evaluation of referenced scheduling…

Performance analysis of multi‐criteria CAC for distributed access point selection in WLANs

I‐Shyan Hwang, Chien‐An Chen

Wireless local area networks (WLANs) are the predominant option for broadband wireless access network, and multiple access points (APs) will be much more available for wireless…

Logical coordinate assignment for geographic routing in wireless sensor networks

Jang‐Ping Sheu, Yu‐Chia Chang, Gang‐Hua Song

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…

A weighted multilateration positioning method for wireless sensor networks

Yu‐He Gau, Hung‐Chi Chu, Rong‐Hong Jan

Localization problem is one of the most important research issues for wireless sensor networks (WSNs). The purpose of this paper is to present a two‐phase localization algorithm…

Energy‐proportional routing for lifetime extension of clustering‐based wireless sensor networks

Chao‐Lieh Chen, Kuan‐Rong Lee, Yau‐Hwang Kuo

The purpose of this paper is to propose an energy‐proportional routing (EPR) algorithm, which effectively extends the lifetimes of sensor networks.
