Description

It is important to ensure an efficient data transfer between the nodes in wireless communication. In D2D communications, each device should first discover nearby devices, which have mobile applications of interest, by using a discovery protocol. The main objective of this project is to maximize the bandwidth efficiency. Bandwidth efficiency is nothing but how effectively the nodes use the bandwidth. If some bandwidth is remains in some node, we have to make use of that bandwidth. It also reduce false positive rate. The proposed discovery protocol makes use of a short discovery code that contains compressed information of mobile applications in a device. A discovery code is generated by using either a hash function or a Bloom filter. When a device receives a discovery code broadcast by another device, the device can approximately find out the mobile applications in the other device.
