been growing interest in recent years. USN are envisioned to
monitor pollution and harmful algal blooms, provide an early
warning for natural disasters, aid in surveillance applications
for defense purposes, and assist in finding and recovering
wrecked ships and aircrafts. Most USN requires wireless
communication and currently acoustics is the primary
modality of choice even though it presents a difficult channel.
To try and cope with the challenges of the channel many MAC
protocols and PHY layer techniques have been proposed. In
this thesis the author presents a research platform that allows
developers to easily implement and compare their protocols in
an underwater network and configure them at runtime. The
platform was created using widely supported software that has
been successfully used in terrestrial radio and network
development. The flexibility of development tools such as
software defined radio has provided the ability for rapid
growth in the community. This platform adapts some of these
tools to work well with the underwater environment while
maintaining flexibility, ultimately providing an end-to-end
networking approach for underwater acoustic development.
The author has demonstrated how this platform can be used by
developing a protocol for underwater dynamic channel
assignment in USNs. The network resources of free spaces,
can equivalently use in underwater considering losses.
In addition to developing a highly configurable
acoustic modem, this thesis also introduces a card based
design for optical communication. Optics is used for a low
power, short distance alternative to the high power acoustics.
Both platforms have been demonstrated in real world
scenarios and can be controlled from an embedded Linux
platform allowing for a single application to have access to
both modalities simultaneously.

It is based on interviews and focus group discussions with general people and government representatives, as well as a detailed review of the existing literature. The study found that local government institutions in Bangladesh are very weak in providing basic services to the citizens and in promoting good governance to their constituencies due to a variety of constraints, including a lack of revenues, a low level of human capital in the local government bodies, the absence of participatory decision-making, and the lack accountability and transparency. The existing problems in transparency and accountability at local level finance are interrelated to a lack of people's participation in the budgeting process and weak monitoring mechanism. The study recommends that (1) local authority should have enough power to generate revenue and to exercise financial autonomy, which also implies that grants from the government should be adequate, (2) every work area should be independently audited and supervised by the central government, and (3) there needs to be far more dissemination of local financial budgets.
