The most well-known present scheme which providesQoSsupportiveMACforWLANs(WirelessLocalAreaNetworks) is HCF [2]. The latter comprises a distributedprotocol known as EDCA and an optional resource reserva-tion centralized protocol called HCCA. EDCA is capable ofdifferentiating traffic; however, it suffers[r]

pared with OFDM systems, OFDM/SDMA systems havelarger capacity but are also more complex. In [10], sev-eral efficient approaches are proposed to adopt SDMA inOFDM systems. In [11], an algorithm is proposed to allo-cate spatially separable users in the same subchannel by ad-justing[r]

What Are the Threats? One of my favorite quotes is from Sun Tzu's The Art of War: If you know the enemy and know yourself, you need not fear the result of a hundred battles. If you know yourself but not the enemy, for every victory gained you will also suffer a defeat. If you kn[r]

security designers keep track of what threats management chooses to respond to, and which threats it deems acceptable. Risk management is covered in greater detail in Module 4, “Analyzing Security Risks.” Students may feel overwhelmed when presented with the task of class[r]

Recently, the problem of joint optimization of dataflow routing and resource allocation in wireless networkswhen network coding is used in the network layer has alsobecome of interest. Minimum cost multicast problem hasbeen considered in [15, 16]. They[r]
