This technical note considers the problem of resource allocation in linear feedback control system with output disturbance. By decomposing the information rate in the feedback communication channel, the channel resource allocation is thoroughly analyzed. The results show that certain amount of resource is used to transmit the output disturbance and this resource allocation is independent from f...

In this paper a multi-channel MAC protocol with dynamic channel allocation (MMAC-DCA) in CDMA Ad Hoc networks is proposed. Under MMAC-DCA, the service sub-channels are dynamically allocated by the RTS/CTS dialogue on the common sub-channel, only when a node has a packet to transmit. In addition, a Markov mode is presented to analyze the performance of MMAC-DCA. key words: Ad Hoc networks, dynam...

Technological advances and rapid development of handheld wireless terminals have facilitated the rapid growth of wireless communications and mobile computing. Essentially we have a limited resource transmission spectrum, which must be shared by several users. Since the available frequency spectrum is limited the channels must be reused as much as possible in order to increase the system capacit...

Inorder to enhance the capacity and output of a downlink orthogonal frequency division multiple access(OFDMA) network, it is essential to perform appropriate resource allocation. Correct resource allocation suggests that finding best subchannel and power allocation for each and every user. Therefore here associate algorithm is proposed to attain this. Initial of all sub-channel allocation is pe...

—To solve the problem of channel allocation in multi-radio Wireless Sensor Networks (WSNs), this paper proposed distributed channel allocation and adaptive update scheme based on channel utilization and Data Transmission Success Rate (DTSR). First, node periodically calculates the channel utilization and DTSR on each data channel. Second, node can adaptively adjust the statistical period and u...

One important quantity in assessing the viability of local, autonomous, dynamic channel allocation for microcellular systems is user capacity, defined as the average number of users per channel per cell. Here, we determine the capacity for infinite linear and planar arrays of microcells using a very idealized environment. In particular, propagation and interference considerations are simply rep...
