Time synchronization is critical for parallel and distributed simulation (PADS). In this paper we first compare the two main synchronization mechanisms in PADS, namely conservative and optimistic protocols. Then we propose a Minimum Time Buckets synchronization algorithm, which can optimistically schedule events without sending anti-messages. Comparing to the well-known Breathing Time Bucket (MTB)...
Neighbor discovery is the very first step for many mobile applications. Previous neighbor discovery protocols that use single channel may be failed when faced with unreliable channel environment, whereas most of multi-channel schemes do not focus on neighbor discovery in low duty cycle wireless networks. The key challenge for multi-channel slotted neighbor discovery is how to effectively assign the...
