Table 1: Comparison of several routing protocols for ad hoc networks.

in Power-Aware Routing in Mobile Ad Hoc Networks
by Mike Woo, Suresh Singh, C. S. Raghavendra
"... In PAGE 3: ... Of course, the routes are not necessarily the shortest. The salient features of these protocols is summarized in Table1 . In this table, we have classi ed the protocols according to the metrics used for route optimization, the message overhead in determining routes, the type of protocol used and its convergence goals (active refers to a protocol that runs until all routing tables are consistent while passive refers to an algorithm that determines routes based on an as-needed basis).... ..."

Table 3 Local Features on Ad-Hoc Protocols

in Intrusion Detection Techniques for Mobile Wireless Networks
by Yongguang Zhang, Wenke Lee, Yi-an Huang
"... In PAGE 11: ... For instance, PCH is the percentage of change in number of total intermediate hops from all source routes cached in DSR, but the per- centage of change of sum of metrics to all reachable destinations in DSDV and AODV. We used the following features in Table3 to build models on ad-hoc routing protocols. Notice features are collected from three sources, route cache, tra c pattern, and movement information of the host.... ..."

Table 1. Operational requirements of the surveyed secure ad hoc routing solutions.

in Abstract
by Patroklos G. Argyroudis
"... In PAGE 25: ...The surveyed protocols base their proposed solutions to the problem of secure ad hoc routing on certain assumptions and operational requirements. Table1 summarizes the results of the comparison regarding this aspect and forms a basis for the discussion in this section. Table 1.... ..."

Table 3. Comparison of multicast routing protocols for mobile ad hoc netowrks

in unknown title
by unknown authors 2005
"... In PAGE 31: ... Table3 gives comparison of typical multicast routing protocols for mobile ad hoc networks. Metrics used for comparison are the multicast delivery structure, how to acquire and maintain routing information, whether they are loop-free, the dependency on underlying unicast routing protocol, is the control packet flooding being used, the requirement for periodic control messages, the routing hierarchy and their scalability.... ..."

Table 2. Summary of our system routing ad-hoc

"... In PAGE 7: ...articularly long documents. This results in such documents being placed in a high ranking. Another problem is that noun phrases which automatically extracted from topic, sometimes retrieves insufficient documents. Table2 shows the summary of our system. Concerning points of improvement from now, we are thinking of another weight calculation method rather than the use of deviation.... ..."

Table 4: Overlap of submitted results. Ad Hoc Routing

in Overview of the Sixth Text REtrieval Conference (TREC-6)
by Ellen M. Voorhees, Donna Harman 1997
"... In PAGE 10: ....3.1 Overlap The e ect of pooling can be measured by examining the overlap of retrieved documents. Table4 summa- rizes the amount of overlap in the ad hoc and routing pools for each of the six TRECs. The rst column in the table gives the maximum possible size of the pool.... In PAGE 10: ... Starting in TREC-4, various tracks also contributed documents to the ad hoc or routing pools. These are broken out in the appropriate rows within Table4 . The order of the tracks is signi cant in the table|a document retrieved in a track listed later is not counted for that track if the document was also retrieved by a track listed earlier.... In PAGE 10: ... An investigation of the size of the pools if everyone apos;s second choice were also merged into the pools showed that the pools would be too large for the assessors to nish in the available time.) Table4 shows that the average number of relevant documents per topic continues to decrease over the years. NIST has deliberately chosen more tightly- focused topics to better guarantee the completeness of the relevance assessments.... ..."
