In this paper we study a model of joint congestion control and routing in a ring network of sources with a single destination at the center (Figure 2). A utility maximization problem subject to routing constraints is posed and equations for its solution are presented. The distribution of traffic on routes available to a source is subject to an entropy constraint that controls the path diversity or...
For industrial applications, real-time performance is a critical issue of wireless sensor network. IEEE802.15.4 protocol has greater potential compared with other protocols. However, it can??t meet the strict requirements of real-time performance in industrial environment. After analyzing the demands of versatile applications in industrial environment and guaranteed time slots (GTS) mechanism in the...
