摘要优化方法为设计更好的计算机网络服务质量保证机制提供了有力的理论支持.
相较于传统启发式的网络设计方法, 优化方法可以从理论上找到问题的最优解 …

Radio Frequency Identification (RFID) tagging is now used by the department of defense
and many of the world's largest retailers including Wal-Mart. As RFID continues to infiltrate …

We consider a heterogeneous sensor network in which nodes are to be deployed over a unit
area for the purpose of surveillance. An aircraft visits the area periodically and gathers data …

We consider the joint optimal design of the physical, medium access control (MAC), and
routing layers to maximize the lifetime of energy-constrained wireless sensor networks. The …

A sensor network of nodes with wireless transceiver capabilities and limited energy is
considered. We propose distributed algorithms to compute an optimal routing scheme that …

Abstract Disaster Area Network (DAN) is very crucial in case of natural or man-made
disasters. During state of emergency, a rapidly deployable network is the highest priority to …

In multihop wireless sensor networks that are often characterized by many-to-one
(convergecast) traffic patterns, problems related to energy imbalance among sensors often …

Transmit power control is a prototypical example of a cross-layer design problem. The
transmit power level affects signal quality and, thus, impacts the physical layer, determines …

Optimizing the energy consumption in wireless sensor networks has recently become the
most important performance objective. We assume the sensor network model in which …

Unlike traditional routing schemes that route all traffic along a single path, multipath routing
strategies split the traffic among several paths in order to ease congestion. It has been …
