Wireless communication multimedia applications are increasing day by day in traffic, security, agriculture and health care service sectors. Multimedia communication itself involves a complex process that consumes more power at transmitter and receiver. Our research evolves start to end layer design margin to reduce power consumption and increase multimedia data quality. In this we propose the MIMO-OFDM system with a hybrid fuzzy GWO technique to minimize consumed power. Cross-layer margins are optimized by Grey Wolf Optimizer with a fuzzy algorithm that analysed compression and communication techniques for wireless communication. This cross-layer design provides power reduction and energy-efficient multimedia data transmission in the MIMO-OFDM system. We use a fuzzy approach for the fast processing speed of GWO

Interactive 3D

The explosive development of Internet and wireless communication has made personal communication more convenient. People can use a handy wireless device to transfer different kinds of data such as voice data, text data, and multimedia data. Multimedia streaming, video conferencing, and on-line interactive 3D games are expected to attract an increasing number of users in the future. The bandwidth requirement would be high and the heterogeneous terminals would generally provide limited resource, such as low processing power, low battery life and limited data rate capabilities. These applications would be the major challenge for wireless networks. Although the traditional layered protocol stacks have been used for many years, they are not suitable for the next generation wireless networks and the mobile systems. Due to the time varying transmission of the wireless channel and the dynamic resource requirements of different application, the traditional layered approach to the mobile multimedia communication is full of challenges to meet the user requirement on performance and efficiency. Cross-layer design is an interesting research topic that actively exploits the dependence between different protocol layers to obtain performance gains. The authors performed a survey and introduced the cross-layer design principles and issues for different research topics, including QoS, mobility, security, application, and the next generation wireless communication.

Wireless sensor networks require energy-efficient and robust routingprotocols. Most routing protocols for sensor networks try to extendnetwork lifetime by minimizing the energy consumption, but have not taken the network reliability into account. In this paper, we analyze the fault models and propose an ENergy-aware FAult-tolerantRouting scheme, termed as ENFAR. Firstly a link-based uniform fault model is presented, and we adopt a cross-layer design to measurethe transmission delay so as to detect the failed nodes.
