In recent years, service-oriented systems are becoming
increasingly complex, with growing size and heterogeneity.
Developing and deploying such large-scale systems present several challenges, such as reliability, reproducibility, handling failures on infrastructure, scaling deployment time as composition size grows, coordinating deployment among multiple organizations, dependency management, and supporting requirements of adaptable systems. However, many organizations still rely on manual deployment processes, which imposes difficulties in overcoming such challenges. In this paper, we propose a flexible and extensible middleware solution that addresses the challenges present in the large-scale deployment of service compositions. The CHOReOS Enactment Engine is a robust middleware infrastructure to automate the deployment of large-scale service compositions. We describe the middleware architecture and implementation and then present experimental results demonstrating the feasibility of our approach.

Fog computing has been regarded as an ideal platform for distributed and diverse IoT applications. Fog environment consists of a network of fog nodes and IoT applications are composed of containerized microservices communicating with each other. Distribution and optimization of containerized IoT applications in the fog environment is a recent line of research. Our work took Kubernetes as an orchestrator that instantiates, manages, and terminates containers in multiple-host environments for IoT applications, where each host acts as a fog node. This paper demonstrates the industrial feasibility and practicality of deploying and managing containerized IoT applications on real devices (raspberry pis and PCs) by utilizing commercial software tools (Docker, WeaveNet). The demonstration will show that the application's functionality is not affected by the distribution of communicating microservices on different nodes.

Small-cell-deployments have pulled cellular operators to boost coverage and capacity in high-demand areas (for example, downtown hot spots). The location of these small cells (SCs) should be determined in order to achieve successful deployments. In this paper, we propose a new approach that optimizes small cells deployment in cellular networks to achieve three objectives: reduce the total cost of network installation, balancing the allocation of resources, i.e. placement of each SC and their transmitted power, and providing optimal coverage area with a lower amount of interference between adjacent stations. An accurate formula was obtained to determine the optimum number of SC deployment (NSC). Finally, we derive a mathematical expression to calculate the critical-handoff-point (CHP) for neighboring wireless stations.

In recent years there has been an exponential growth of
e
-
Governance in India. It is growing to such a
scale
that requires full attention
of the
Government
to ensure
collaboration
among
different
government
departments, private sector
s
and
Non

Go
vernmental Organisations(NGOs)
.
In order to
achieve
successful
e
-
Governance, Government has to
facilitate delivery of services to citizens, b
usiness
houses
and other
public or private
organisations
according to
their requirements.
In this paper, we have pr
oposed
integration of different government departments using a Service Oriented e

Governance(SOeGov)
approach with web service
s
technology and Service Oriented Architecture(SOA).
The proposed approach
can be effectively
used for
achieving
integration and
interoperability
in an e
-
Governance system
.
We have
demonstrate
d
the working of
our
approach
through
a case study
where integration of several departments
of the provincial Government of Odisha (India) has been made possible.
