| Abstract | Mobile adhoc networks (MANETs) are networks that can be used to provide In-
ternet connections in those areas that do not have xed communication infrastructures.
MANETs can use mobile phones to make a temporary communication infrastructure.
However, the nodes inside s MANET can move, and may cause a disconnection of the
MANET into many fragments called Disconnected MANETs (DMANETs). As a re-
sult, some node pairs cannot make connections to each other. This thesis, investigates
the deployment of additional nodes called mobile relay nodes between the boundaries
of DMANETs to improve the connectivity. The proposed framework, called density
deployment, depends on the density of normal mobile nodes in each sub-area. In the
framework, the mobile relay nodes move once every location update period to the next
optimal locations. Moreover, the density deployment is further improved by adding
the greedy algorithm to assign which relay node should move to which location. Under
the greedy algorithm, each mobile relay node is assigned to move to the next location
that is closest to the current location, starting with the node with the minimum dis-
tance. Finally, simulations are carried out to evaluate the network performance under
the density deployment in terms of packet delivery ratio (PDR), throughput, control
overhead and normalized routing load. |
