The need and importance of Smart Spaces have been potentially realized by the researchers due to its applicability in the current lifestyle. Opportunistic network, a successor of mobile ad hoc networks and a budding technology of network, is a best-suited technology for implementing Smart Spaces due to its wide range of applications in real-life scenarios ranging from building smart cities to interplanetary communication. There are numerous routing protocols which are available in opportunistic network, each having their pros and cons; however, no research till the time of listing has been done which can quantitatively demonstrate the maximum performance of these protocols and standardize the comparison of opportunistic routing protocols which has been a major cause of ambiguous performance evaluation studies. The work here presents a categorical view of the opportunistic routing protocol family and thereby compares and contrasts the various simulators suited for their simulation. Thereafter, the most popular protocols (selecting at least one protocol from each category) are compared based on node density on as many as 8 standard performance metrics using ONE simulator to observe their scalability, realism, and comparability. The work concludes by presenting the merits and demerits of each of the protocols discussed as well as specifying the best routing protocol among all the available protocols for Smart Spaces with maximum output. It is believed that the results achieved by the implemented methodology will help future researchers to choose appropriate routing protocol to delve into their research under different scenarios.

节点密度对智能空间机会网络中路由协议QoS参数的影响

由于智能空间在当前生活方式中的适用性，研究人员已经潜在地意识到了其必要性和重要性。机会网络是移动自组织网络的后继者，也是网络的萌芽技术，由于它在从构建智能城市到星际通信的现实场景中具有广泛的应用，因此它是实现智能空间的最适合的技术。机会网络中有许多可用的路由协议，各有其优缺点。但是，直到上市之时为止，还没有任何研究能够定量地证明这些协议的最大性能，并规范了机会路由协议的比较，这是导致性能评估研究模糊的主要原因。这里的工作给出了机会路由协议系列的分类视图，从而比较和对比了适合其仿真的各种仿真器。此后，使用ONE模拟器根据多达8个标准性能指标上的节点密度比较最流行的协议（从每个类别中选择至少一个协议），以观察其可伸缩性，真实性和可比性。最后，工作提出了所讨论的每种协议的优缺点，并在所有可用的智能空间协议中以最大的输出量指定了最佳路由协议。据信，通过实施的方法所获得的结果将有助于未来的研究人员选择合适的路由协议，以深入研究不同情况下的研究。
