U-Connect
v3 v4 9 9 = Protocol Overview = 10 10 U-Connect is an unified protocol to address both the symmetric and asymmetric asynchronous neighbor discovery problems. 11 Consider a protocol in which a node picks a prime number ''p'' and stays active for ''1'' every ''p'' slots. Any two primes are by definition 12 relatively prime with each other. Hence, two nodes choosing different primes will discover one another. If the nodes choose the same pair of 11 The intuition behind the protocol design is as follows. Consider a protocol in which a node picks a prime number ''p'' and stays active for ''1'' slot every ''p'' slots. Any two primes are by definition relatively prime with each other. Hence, two nodes choosing different primes will discover one another. If the nodes choose the same pair of 13 12 primes, discovery can still be ensured by each node staying active for slightly longer than half the prime period ''p''. 14 15 13 16 14 The protocol has been implemented on a custom designed light-weight, small and rechargeable mobile sensor-networking hardware platform called '''FireFly-Badge'''. In the implementation, the node listens at the slots that are multiples of ''p''. This operation is fundamentally ''Low
