Abstract: A method and apparatus for a collision-free carrier sense multiple access (CSMA) are provided. The method of a node associated with a beacon enabled carrier sense multiple access (CSMA)-based wireless communication network through an access point (AP) includes receiving a beacon from the AP, the beacon comprising a back-off prime number and a beacon random number, and generating a back-off interval based on the beacon random number, the back-off prime number, a mapped identification (ID) of the node, and a current time slot of a frame of the beacon. The method and apparatus provide a collision-free CSMA scheme for a beacon enabled CSMA-based wireless communication network. In the collision-free CSMA scheme, uniformly distributed back-off intervals may be generated in a distributed fashion at each node for a CSMA-based wireless communication network. The back-off intervals may be correlated among the nodes even though the nodes do not communicate with each other.

Abstract: The embodiments herein disclose methods and systems for reducing network protocol latency for at least one application on an electronic device, a method includes pre-resolving a plurality of Domain Name System (DNS) queries for the at least one application. The plurality of DNS queries is pre-resolved before triggering at least one DNS resolution query from the at least one application. The method includes pre-connecting a plurality of TCP connections of the at least one application with at least one Transmission Control Protocol (TCP) server. The plurality of TCP connections are pre-connected before triggering at least one TCP connection request from the at least one application. The method includes exchanging a plurality of secure certificates with the at least one TCP server to secure the plurality of pre-connected TCP connections. The secure certificates are exchanged before receiving at least one request from the at least one application for secure certificate negotiation.
