All Nodes Sense data2. Every Node broadcasts data to neighbors & each neighbor broadcasts received data & its own data to its neighbors3. Every time a robot detects another robot in range, then all data within its buffer is broadcast to the new neighbor and to its neighbors and vice-versa4. Each robot’s data is marked with its IP, when 0 receives data from all robots then the sampling for that period is complete. 0 is pre-programmed to know all IP addresses before hand.Test BedSpatial Distribution in Bounded RegionSimulation ResultsDiscussion and Future WorkIssue : Buffer Memory Requirement : Unbounded MemoryStrategy : Circular BufferDisadvantage : Erasure of dataFood For Thought??When 2 robots in each others range Both transmit data to each other.. Result: Data corruption due to interference of Broadcast??Thank
