MotionCast: A Survey on the Capacity Scaling of Wireless Networks

Abstract

Wireless network has been studied for several years. As a basic characteristic, capacity draw a lot of attentions from thousands of researchers and many significant improvements have been achieved under different assumptions or models. This chapter will give you a global perspective about the researches on capacity in the past years. We set up a system model to analyze and compare the results for wireless networks. First, we introduce the network models and some important definitions which have been widely used in the past researches. Then we discuss the capacity-delay tradeoff problems in wireless networks. After that, the capacity in random networks and arbitrary networks are illustrated respectively. Furthermore, based on the capacity discussion, we give some points on the factors that can have a great impact on capacity. In the end of this chapter, we come up with some popular techniques and show how they contribute to capacity respectively.
