With the 802.11 WLAN multimedia applications (Video, Audio, realtime voice over IP,...) increasing, providing Quality of Service (QoS) support becomes very important since the original standard doesn’t take QoS into account. The standard offers access to the wireless users only regarding physical considerations. This can lead to overloaded access points(More)
In this paper, we present and evaluate a hardware implementation for user-driven and packet-loss tolerant image compression, especially designed to enable low-power image compression and communication over wireless sensors networks (WSNs). The proposed compression scheme, presented as a CMOS circuit, is intended to be embedded in the camera sensor. It will(More)
Recently there is a growing interest in the internet and multimedia wireless networking where the bandwidth and the Quality of Service ( QoS) should be managed with careful. The performances of applications built on these systems depend on bandwidth availability that arises as the most limit of this solution. In fact, the IEEE 802.11 standards do not(More)
In this paper, a low-complexity image compression scheme for energy-constrained Wireless Camera Sensor Networks (WCSN) is presented and its hardware implementation cost for FPGA solution is evaluated. The main purpose of this FPGA circuit is to relieve the main microcontroller in the camera sensor node of the image compression tasks and to achieve highspeed(More)

The increasing complexity of integrated circuits and application requirements drive the research of new on-chip interconnection architectures. A network on chip draws on concepts inherited from distributed systems and computer networks subject areas to interconnect IP cores in a structured and scalable way. The main goal pursued is to achieve superior(More)
In the few last years, the deployment of IEEE 802.11 WLAN in hotspots environment had becoming a useful solution providing practical and attractive communication characteristics. However the problem of user bandwidth availability arises as one of the most limit of this solution. In fact, the IEEE 802.11 standards do not provide any mechanism of loading(More)
