What is Middleware

7

Common Features Of Middleware Connection and message delivery Transformation Detection and storage Optimization Security Operation support

8

The Limitations of Mobile Computing

1. Mobile Devices2. Network Connection and 3. Physical Host Mobility

Due to these limitations, conventional middleware technologies designed for fixed distributed systems are not prepared to support mobile systems

9

Requirements for Mobile Computing

Dynamic reconfiguration

Adaptions

Asynchronous interaction

Context-awareness

Lightweight middleware

Types of Middleware Technologies

Reflective Middleware

Tuple Space Middleware

Context-Aware Middleware

Event-Based Middleware

Context Aware Middleware Why Context Aware Middleware

Current Context Aware Middlewarefree developers from the implementation of low-level details related to the network, like

Concurrency ControlTransaction managementNetwork Communication

So we can focus on application requirements.

Context-Aware Middleware Issues Issues of Context aware middleware

With the birth of context-aware middleware many issues came out, like

Security, Balance of user control, Sensing the context and conflicts.

we examine the balance of user control in the new middleware approach.

17

Proposed PlanBalance of user control,

However, context-aware applications may not always adapt as the user expects, and may cause users to feel loss of control over the behavior of their applications
