This paper studies the problem of relay-assisted user scheduling for downlink wireless transmission. The transmitting base station or access point employs hybrid automatic-repeat-request (ARQ) transmission with the possible assistance of a set of fixed relays to serve a set of mobile users. By minimizing a cost function that depends on the queue lengths at the base station and the number of ret...

Sensor webs consisting of nodes with limited battery power and wireless communications are deployed to collect useful information from the field. Gathering sensed information in an energy efficient manner is critical to operate the sensor network for a long period of time. In [3] a data collection problem is defined where, in a round of communication, each sensor node has a packet to be sent to...

Wireless Sensor Networks consists of no. of micro sensor nodes to monitor a remote environment by using aggregated data from individual nodes and transfer this data to the base station for further purpose. Here the energy of operated nodes is susceptible store of the Wireless Sensor Network, which is useless at a rate when information is transmitted, because transmission energy is reliant on th...

The benefits of using mobile base station to prolong sensor network lifetime have been well recognized. However, due to the complexity of the problem (time-dependent network topology and traffic routing), theoretical performance limits and provably optimal algorithms remain difficult to develop. This paper fills this important gap by contributing theoretical results regarding the optimal moveme...

In wireless sensor network (WSN), sensor nodes are partitioned into clusters in order to gather information more efficiently in terms of energy consumption. In clustered networks, each node transmits acquired data to a cluster-head which the nodes belong to. After a cluster-head collects all the data from member nodes, it transmits the data to the base station (sink) in aggregated manner. This ...

Nowadays, the development of 5G, edge computing, NFV and other technologies brought by surge network traffic will become a new challenge to refinement, automation, intelligent operation maintenance management network. In order meet this challenge, it is necessary accurately perceive application-level at multiple levels, such as network, MAN backbone reduce error predicting flow data, neural alg...

In this paper, we model the cellular network consisting of aerial base stations (ABSs) which follow homogeneous Poisson Point Process (PPP) and an independent collection random users is considered. We assume that each user communicates with closest ABS. particular, deal interference signals Laplace transform. As a result, can obtain tractable expression coverage probability. have found there ma...
