在本文中，我们提出了一种方法，用于共享多个节点之间的控制数据包的握手，我们称之为一个混合的发送者和接收者发起（HSR）协议计划。握手共享可以通过邀请邻居加入当前握手并允许他们发送数据包而无需额外握手来实现。因此，HSR可以减少握手期间控制分组交换所涉及的信令开销，以及解决节点之间的空间不公平性问题。从操作的角度来看，HSR类似于被称为使用反向机会分组附加（ROPA）的介质访问控制（MAC）协议的众所周知的握手共享方案。然而，在ROPA的等待时间是不可控的接收器的邻居，因此意外的冲突可能会发生在接收器由于隐藏的邻居，而所提出的方案允许所有节点，以避免隐藏节点引起的冲突，根据精心计算的等待时间。我们的计算机模拟表明，HSR优于ROPA的吞吐量和延迟分别约9.65%和11.36%。
In this paper, we propose a method for sharing the handshakes of control packets among multiple nodes, which we call a hybrid sender- and receiver-initiated (HSR) protocol scheme. Handshake-sharing can be achieved by inviting neighbors to join the current handshake and by allowing them to send their data packets without requiring extra handshakes. Thus, HSR can reduce the signaling overhead involved in control packet exchanges during handshakes, as well as resolve the spatial unfairness problem between nodes. From an operational perspective, HSR resembles the well-known handshake-sharing scheme referred to as the medium access control (MAC) protocol using reverse opportunistic packet appending (ROPA). However, in ROPA the waiting time is not controllable for the receiver’s neighbors and thus unexpected collisions may occur at the receiver due to hidden neighbors, whereas the proposed scheme allows all nodes to avoid hidden-node-induced collisions according to an elaborately calculated waiting time. Our computer simulations demonstrated that HSR outperforms ROPA with respect to both the throughput and delay by around 9.65% and 11.36%, respectively.
