Querying Network Graphs with Recursive Queries
... commonly-used recursive queries using PIER. These queries
are variants of the transitive closure query, which can be used
to compute reachability information within a graph. We will
further show how our execution techniques can be generalized
to support dynamic graphs, and to facilitate work sharing ...
... as follows: n0 n2, n1 n2 and n2 n3. Apply TCP agent between n0-n3 and UDP
between n1-n3. Apply relevant applications over TCP and UDP agents changing the
parameter and determine the number of packets sent by TCP / UDP. (n0, n1 and n3 are
nodes and n2 is router.). .............................. ...

... localized, i.e., each node uses only the information that is one or two hops away. The problem of
minimizing the total energy consumption for the whole network is NP-hard in both two and three
dimensional space [7,8]. In addition, if the WSN consists thousands of nodes, it is difficult to calculate
QU-RPL: Queue Utilization based RPL for Load
... Cisco’s field area network (FAN) solution for smart grids 
(CG-Mesh) is a good commercial example that uses RPL in
LLNs. It is based on the IPv6 architecture, and uses IEEE
802.15.4g/e at the PHY and MAC layer to form LLNs. On top
of that, it uses 6LoWPAN, RPL, and IPv6 to provide end-toend two-w ...

CTC Information and Shortcuts
... Network view shows all the nodes in a ring. A Superuser can set up this feature so each user will see
the same network view, and users can create a custom view with maps. This view provides access to

Self Organizing Wireless Mesh Networks
... We incorporated these metrics in an ad hoc routing protocol based on DSR. We deployed this protocol on a 23-node
wireless testbed, and experimented with various traﬃc scenarios such as long-lived TCP ﬂows, multiple simultaneous

a scenario in ...
Extending AODV to enforce participation in a Mobile Ad

in these scenarios. For maintaining the peer-to-peer and co-operative nature of ad-hoc mobile
networks i ...
