Smart electricity consumption technology is an important part of smart grid, and task scheduling of household electricity consumption is one of the important applications of smart electricity consumption researches in household. However, the lack of efficient intelligent scheduling optimization algorithms has restricted its application. The task of electricity consumption is defined according to the...
In wireless sensor networks, some sensor nodes are put in sleep mode while other sensor nodes are in active mode for sensing and communication tasks in order to reduce energy consumption and extend network lifetime. This approach is a special case (k=2) of a randomized scheduling algorithm, in which k subsets of sensors work alternatively. In this paper, we first study the randomized scheduling algorithm...
The paper first shows that TCP's congestion control mechanism based on packet-loss does not adapt well in multihop ad hoc networks. Then by modeling the MAC protocol, the interaction between the MAC protocol and TCP is pointed: the function of the MAC layer is to try its best to look for a group mutually exclusive job scheduling for the loaded traffic, whereas the function of transport layer is to...
Wireless sensor networks are widely used for monitoring applications. The monitored area and the intrusion object are mostly three dimensional. In this paper, we are particularly interested in a sensor network used for monitoring a field to detect intrusion objects such as submarine in some sea area, or goods on shelves in warehouse. In these applications, sensors float in different depth of water...
Wireless sensor networks have many applications. In this paper, we are particularly interested in a sensor network which is used for monitoring a field to detect intrusion objects such as enemy tanks, enemy cars, etc. Since sensor nodes have limited energy supply, sensor networks may be configured to put some sensor nodes in sleep mode to save energy. This is a special case of a randomized scheduling...
In wireless sensor networks, in order to minimize energy consumption and extend network lifetime, some sensors are put in the sleep mode while the other sensor nodes are in the active mode for the sensing and communication tasks. In a randomized scheduling algorithm, a set of sensors work alternatively. In this paper, we provide an analytical model for the randomized scheduling algorithm, and derive...
