Mobile computing topics
The devices in the network may not be able to access the WLAN leading to network latency and bad user experience. In other words, it refers to ways by which internet is embedded to different devices. Spatial Multiplexing — Spatial multiplexing is a technique to increase the channel capacity. Therefore, we propose to evaluate the per-hop delay using a metric defined on the contentions detected by a wireless node. Small Devices — Smaller but powerful devices are built which will have high scalability and versatility. It is a decentralized wireless network. Sleep Mode keeps the radio in standby mode. It is a wireless network of two or more devices and uses high-frequency radio waves for communication. To improve the efficiency of data access in wireless mobile networks, mobile data management is one of the most important topics in mobile computing. Battery Limitations — A lot of battery power is consumed while accessing the wireless communication network. In partial mesh topology, some of the nodes are connected to all other nodes while other nodes are connected to those nodes with which they want to exchange data. We propose to achieve an optimal tradeoff between caching overhead and total access delay by properly selecting a subset of wireless nodes as cache nodes. In offices, real-time data can be accessed using this wireless network.
Sensors — Sensors are essential components of IoT enabled devices. Retransmission leads to lower performance. Simulation results show that DRCC achieves much better performance than the existing best cooperative caching strategy in MANETs in terms of average query delay, caching overheads, and query success ratio.
PolyU Library Call No. MIMO technology is also used in non-wireless communication systems like home networking standard to transmit multiple signals.
There are two modes to conserve the power. WLAN can be used to communicate with other doctors in case of emergency situations. Simulation results show that GosCC achieves much better performance than other cooperative caching schemes, in terms of average interruption intervals and average interruption times, while sacrificing acceptable message cost to a certain degree.
In ad hoc nodes use peer to peer method of communication with each other.
GosCC applies the gossiping scheme to guarantee that mobile nodes receive the accurate and timely information for making caching decisions.
