Hi , I am planning on a small project and need help regarding its feasibility. I have a few wireless mobile devices (could be phones and laptops) which periodically broadcast packets and also each device listens for other broadcasts. Any device in range should receive the broadcasted data (no need to reply or acknowledge or re-broadcast) , its ad hoc, in fact I don't even need to connect. 1.To perform this can I just send UDP packets with address 255.255.255.255, I heard this was deprecated. If so how do I achieve this? There is no underlying network topology so I cannot rely on multicast or is there a way? 2.If there are 100 such devices, all in wireless range, each 1 performing a periodic broadcast and receive, will it work? will there be too many collisions ? and become infeasible. Each device receiving 70% of the packets is a good performance according to me. Thank You
